Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87370, here are decompositions:

  • 11 + 87359 = 87370
  • 47 + 87323 = 87370
  • 53 + 87317 = 87370
  • 71 + 87299 = 87370
  • 89 + 87281 = 87370
  • 113 + 87257 = 87370
  • 149 + 87221 = 87370
  • 191 + 87179 = 87370

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 87370 first appears in π at position 133,476 of the decimal expansion (the 133,476ordinal-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.
