Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10856, here are decompositions:

  • 3 + 10853 = 10856
  • 19 + 10837 = 10856
  • 67 + 10789 = 10856
  • 103 + 10753 = 10856
  • 127 + 10729 = 10856
  • 193 + 10663 = 10856
  • 199 + 10657 = 10856
  • 229 + 10627 = 10856

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 10856 first appears in π at position 514,239 of the decimal expansion (the 514,239ordinal-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.
