Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 499540, here are decompositions:

  • 17 + 499523 = 499540
  • 47 + 499493 = 499540
  • 59 + 499481 = 499540
  • 101 + 499439 = 499540
  • 137 + 499403 = 499540
  • 149 + 499391 = 499540
  • 179 + 499361 = 499540
  • 191 + 499349 = 499540

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 499,540 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 499540 first appears in π at position 532,956 of the decimal expansion (the 532,956ordinal-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.
