Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990464, here are decompositions:

  • 67 + 990397 = 990464
  • 103 + 990361 = 990464
  • 151 + 990313 = 990464
  • 157 + 990307 = 990464
  • 283 + 990181 = 990464
  • 313 + 990151 = 990464
  • 421 + 990043 = 990464
  • 463 + 990001 = 990464

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 990,464 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 990464 first appears in π at position 206,782 of the decimal expansion (the 206,782ordinal-suffix:nd 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.
