Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 63988, here are decompositions:

  • 11 + 63977 = 63988
  • 59 + 63929 = 63988
  • 131 + 63857 = 63988
  • 149 + 63839 = 63988
  • 179 + 63809 = 63988
  • 227 + 63761 = 63988
  • 251 + 63737 = 63988
  • 269 + 63719 = 63988

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 63988 first appears in π at position 120,344 of the decimal expansion (the 120,344ordinal-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.
