Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987382, here are decompositions:

  • 29 + 987353 = 987382
  • 83 + 987299 = 987382
  • 89 + 987293 = 987382
  • 131 + 987251 = 987382
  • 173 + 987209 = 987382
  • 191 + 987191 = 987382
  • 239 + 987143 = 987382
  • 281 + 987101 = 987382

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 987,382 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 987382 first appears in π at position 365,702 of the decimal expansion (the 365,702ordinal-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.
