Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64256, here are decompositions:

  • 19 + 64237 = 64256
  • 67 + 64189 = 64256
  • 103 + 64153 = 64256
  • 193 + 64063 = 64256
  • 223 + 64033 = 64256
  • 307 + 63949 = 64256
  • 349 + 63907 = 64256
  • 433 + 63823 = 64256

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 64256 first appears in π at position 115,235 of the decimal expansion (the 115,235ordinal-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.
