Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8702492, here are decompositions:

  • 3 + 8702489 = 8702492
  • 61 + 8702431 = 8702492
  • 151 + 8702341 = 8702492
  • 163 + 8702329 = 8702492
  • 181 + 8702311 = 8702492
  • 241 + 8702251 = 8702492
  • 313 + 8702179 = 8702492
  • 541 + 8701951 = 8702492

Showing the first eight; more decompositions exist.

Possible US patent number

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 8,702,492 and was likely granted around 2014.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 8702492 first appears in π at position 544,991 of the decimal expansion (the 544,991ordinal-suffix:st digit after the integer 3).

Search range: the first 1,000,000 fractional digits of π. Any 6-digit-or-shorter string is virtually guaranteed to appear in there — the more interesting signal is the position.
