Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 502720, here are decompositions:

  • 3 + 502717 = 502720
  • 17 + 502703 = 502720
  • 89 + 502631 = 502720
  • 107 + 502613 = 502720
  • 167 + 502553 = 502720
  • 233 + 502487 = 502720
  • 269 + 502451 = 502720
  • 311 + 502409 = 502720

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 502,720 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 502720 first appears in π at position 135,878 of the decimal expansion (the 135,878ordinal-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.
