Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990480, here are decompositions:

  • 11 + 990469 = 990480
  • 17 + 990463 = 990480
  • 83 + 990397 = 990480
  • 97 + 990383 = 990480
  • 103 + 990377 = 990480
  • 109 + 990371 = 990480
  • 131 + 990349 = 990480
  • 149 + 990331 = 990480

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 990,480 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 990480 first appears in π at position 4,549 of the decimal expansion (the 4,549ordinal-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.
