Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71888, here are decompositions:

  • 7 + 71881 = 71888
  • 67 + 71821 = 71888
  • 79 + 71809 = 71888
  • 127 + 71761 = 71888
  • 181 + 71707 = 71888
  • 241 + 71647 = 71888
  • 337 + 71551 = 71888
  • 409 + 71479 = 71888

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 71888 first appears in π at position 128,701 of the decimal expansion (the 128,701ordinal-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.
