Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 508280, here are decompositions:

  • 7 + 508273 = 508280
  • 37 + 508243 = 508280
  • 43 + 508237 = 508280
  • 67 + 508213 = 508280
  • 109 + 508171 = 508280
  • 151 + 508129 = 508280
  • 193 + 508087 = 508280
  • 271 + 508009 = 508280

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 508,280 and was likely granted around 1893.

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

Position in π

The digit sequence 508280 first appears in π at position 128,645 of the decimal expansion (the 128,645ordinal-suffix:th 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.
