Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 29988, here are decompositions:

  • 5 + 29983 = 29988
  • 29 + 29959 = 29988
  • 41 + 29947 = 29988
  • 61 + 29927 = 29988
  • 67 + 29921 = 29988
  • 71 + 29917 = 29988
  • 107 + 29881 = 29988
  • 109 + 29879 = 29988

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 29988 first appears in π at position 52,827 of the decimal expansion (the 52,827ordinal-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.
