Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 63984, here are decompositions:

  • 7 + 63977 = 63984
  • 71 + 63913 = 63984
  • 83 + 63901 = 63984
  • 127 + 63857 = 63984
  • 131 + 63853 = 63984
  • 181 + 63803 = 63984
  • 191 + 63793 = 63984
  • 211 + 63773 = 63984

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 63984 first appears in π at position 238,943 of the decimal expansion (the 238,943ordinal-suffix:rd 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.
