Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8752220, here are decompositions:

  • 13 + 8752207 = 8752220
  • 19 + 8752201 = 8752220
  • 67 + 8752153 = 8752220
  • 97 + 8752123 = 8752220
  • 157 + 8752063 = 8752220
  • 163 + 8752057 = 8752220
  • 181 + 8752039 = 8752220
  • 271 + 8751949 = 8752220

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 8,752,220 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 8752220 first appears in π at position 818,593 of the decimal expansion (the 818,593ordinal-suffix:rd 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.
