Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 63810, here are decompositions:

  • 7 + 63803 = 63810
  • 11 + 63799 = 63810
  • 17 + 63793 = 63810
  • 29 + 63781 = 63810
  • 37 + 63773 = 63810
  • 67 + 63743 = 63810
  • 73 + 63737 = 63810
  • 83 + 63727 = 63810

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 63810 first appears in π at position 15,748 of the decimal expansion (the 15,748ordinal-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.
