Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505898, here are decompositions:

  • 31 + 505867 = 505898
  • 79 + 505819 = 505898
  • 139 + 505759 = 505898
  • 229 + 505669 = 505898
  • 241 + 505657 = 505898
  • 397 + 505501 = 505898
  • 439 + 505459 = 505898
  • 487 + 505411 = 505898

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 505,898 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 505898 first appears in π at position 550,494 of the decimal expansion (the 550,494ordinal-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.
