Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 26988, here are decompositions:

  • 7 + 26981 = 26988
  • 29 + 26959 = 26988
  • 37 + 26951 = 26988
  • 41 + 26947 = 26988
  • 61 + 26927 = 26988
  • 67 + 26921 = 26988
  • 97 + 26891 = 26988
  • 107 + 26881 = 26988

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 26988 first appears in π at position 20,437 of the decimal expansion (the 20,437ordinal-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.
