Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505508, here are decompositions:

  • 7 + 505501 = 505508
  • 61 + 505447 = 505508
  • 79 + 505429 = 505508
  • 97 + 505411 = 505508
  • 109 + 505399 = 505508
  • 139 + 505369 = 505508
  • 151 + 505357 = 505508
  • 181 + 505327 = 505508

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 505,508 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 505508 first appears in π at position 341,988 of the decimal expansion (the 341,988ordinal-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.
