Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55238, here are decompositions:

  • 19 + 55219 = 55238
  • 31 + 55207 = 55238
  • 37 + 55201 = 55238
  • 67 + 55171 = 55238
  • 181 + 55057 = 55238
  • 229 + 55009 = 55238
  • 331 + 54907 = 55238
  • 409 + 54829 = 55238

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 55238 first appears in π at position 85,306 of the decimal expansion (the 85,306ordinal-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.
