Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 988630, here are decompositions:

  • 23 + 988607 = 988630
  • 47 + 988583 = 988630
  • 53 + 988577 = 988630
  • 59 + 988571 = 988630
  • 89 + 988541 = 988630
  • 191 + 988439 = 988630
  • 263 + 988367 = 988630
  • 311 + 988319 = 988630

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 988,630 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 988630 first appears in π at position 117,062 of the decimal expansion (the 117,062ordinal-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.
