Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 988228, here are decompositions:

  • 11 + 988217 = 988228
  • 29 + 988199 = 988228
  • 71 + 988157 = 988228
  • 167 + 988061 = 988228
  • 257 + 987971 = 988228
  • 317 + 987911 = 988228
  • 359 + 987869 = 988228
  • 419 + 987809 = 988228

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 988,228 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 988228 first appears in π at position 11,281 of the decimal expansion (the 11,281ordinal-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.
