Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 63980, here are decompositions:

  • 3 + 63977 = 63980
  • 31 + 63949 = 63980
  • 67 + 63913 = 63980
  • 73 + 63907 = 63980
  • 79 + 63901 = 63980
  • 127 + 63853 = 63980
  • 139 + 63841 = 63980
  • 157 + 63823 = 63980

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 63980 first appears in π at position 27,119 of the decimal expansion (the 27,119ordinal-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.
