Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 999606, here are decompositions:

  • 7 + 999599 = 999606
  • 43 + 999563 = 999606
  • 53 + 999553 = 999606
  • 107 + 999499 = 999606
  • 173 + 999433 = 999606
  • 229 + 999377 = 999606
  • 277 + 999329 = 999606
  • 337 + 999269 = 999606

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 999,606 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 999606 first appears in π at position 51,664 of the decimal expansion (the 51,664ordinal-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.
