Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12588, here are decompositions:

  • 5 + 12583 = 12588
  • 11 + 12577 = 12588
  • 19 + 12569 = 12588
  • 41 + 12547 = 12588
  • 47 + 12541 = 12588
  • 61 + 12527 = 12588
  • 71 + 12517 = 12588
  • 97 + 12491 = 12588

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 12588 first appears in π at position 21,222 of the decimal expansion (the 21,222ordinal-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.
