Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 498820, here are decompositions:

  • 17 + 498803 = 498820
  • 29 + 498791 = 498820
  • 41 + 498779 = 498820
  • 53 + 498767 = 498820
  • 59 + 498761 = 498820
  • 71 + 498749 = 498820
  • 131 + 498689 = 498820
  • 167 + 498653 = 498820

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 498,820 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 498820 first appears in π at position 516,318 of the decimal expansion (the 516,318ordinal-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.
