Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990772, here are decompositions:

  • 5 + 990767 = 990772
  • 11 + 990761 = 990772
  • 53 + 990719 = 990772
  • 173 + 990599 = 990772
  • 179 + 990593 = 990772
  • 269 + 990503 = 990772
  • 383 + 990389 = 990772
  • 389 + 990383 = 990772

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 990,772 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 990772 first appears in π at position 358,493 of the decimal expansion (the 358,493ordinal-suffix:rd 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.
