Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981358, here are decompositions:

  • 47 + 981311 = 981358
  • 71 + 981287 = 981358
  • 137 + 981221 = 981358
  • 149 + 981209 = 981358
  • 281 + 981077 = 981358
  • 347 + 981011 = 981358
  • 359 + 980999 = 981358
  • 401 + 980957 = 981358

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 981,358 and was likely granted around 1910.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 981358 first appears in π at position 333,209 of the decimal expansion (the 333,209ordinal-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.
