Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505500, here are decompositions:

  • 7 + 505493 = 505500
  • 19 + 505481 = 505500
  • 31 + 505469 = 505500
  • 41 + 505459 = 505500
  • 53 + 505447 = 505500
  • 71 + 505429 = 505500
  • 89 + 505411 = 505500
  • 101 + 505399 = 505500

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 505,500 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 505500 first appears in π at position 126,582 of the decimal expansion (the 126,582ordinal-suffix:nd 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.
