Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 999386, here are decompositions:

  • 79 + 999307 = 999386
  • 337 + 999049 = 999386
  • 379 + 999007 = 999386
  • 397 + 998989 = 999386
  • 439 + 998947 = 999386
  • 547 + 998839 = 999386
  • 607 + 998779 = 999386
  • 643 + 998743 = 999386

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 999,386 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 999386 first appears in π at position 933,671 of the decimal expansion (the 933,671ordinal-suffix:st 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.
