Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 499820, here are decompositions:

  • 19 + 499801 = 499820
  • 73 + 499747 = 499820
  • 103 + 499717 = 499820
  • 109 + 499711 = 499820
  • 127 + 499693 = 499820
  • 151 + 499669 = 499820
  • 157 + 499663 = 499820
  • 199 + 499621 = 499820

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 499,820 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 499820 first appears in π at position 777,444 of the decimal expansion (the 777,444ordinal-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.
