Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998646, here are decompositions:

  • 13 + 998633 = 998646
  • 17 + 998629 = 998646
  • 23 + 998623 = 998646
  • 29 + 998617 = 998646
  • 107 + 998539 = 998646
  • 109 + 998537 = 998646
  • 149 + 998497 = 998646
  • 223 + 998423 = 998646

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 998,646 and was likely granted around 1911.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 998646 first appears in π at position 52,358 of the decimal expansion (the 52,358ordinal-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.
