Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505486, here are decompositions:

  • 5 + 505481 = 505486
  • 17 + 505469 = 505486
  • 167 + 505319 = 505486
  • 173 + 505313 = 505486
  • 347 + 505139 = 505486
  • 389 + 505097 = 505486
  • 419 + 505067 = 505486
  • 503 + 504983 = 505486

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 505,486 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 505486 first appears in π at position 617,594 of the decimal expansion (the 617,594ordinal-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.
