Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 988090, here are decompositions:

  • 23 + 988067 = 988090
  • 29 + 988061 = 988090
  • 83 + 988007 = 988090
  • 107 + 987983 = 988090
  • 149 + 987941 = 988090
  • 179 + 987911 = 988090
  • 239 + 987851 = 988090
  • 269 + 987821 = 988090

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 988,090 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 988090 first appears in π at position 646,851 of the decimal expansion (the 646,851ordinal-suffix:st 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.
