Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 56218, here are decompositions:

  • 11 + 56207 = 56218
  • 47 + 56171 = 56218
  • 131 + 56087 = 56218
  • 137 + 56081 = 56218
  • 179 + 56039 = 56218
  • 251 + 55967 = 56218
  • 269 + 55949 = 56218
  • 317 + 55901 = 56218

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 56218 first appears in π at position 136,535 of the decimal expansion (the 136,535ordinal-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.
