Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990430, here are decompositions:

  • 41 + 990389 = 990430
  • 47 + 990383 = 990430
  • 53 + 990377 = 990430
  • 59 + 990371 = 990430
  • 71 + 990359 = 990430
  • 101 + 990329 = 990430
  • 107 + 990323 = 990430
  • 137 + 990293 = 990430

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 990,430 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 990430 first appears in π at position 110,367 of the decimal expansion (the 110,367ordinal-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.
