Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55200, here are decompositions:

  • 29 + 55171 = 55200
  • 37 + 55163 = 55200
  • 53 + 55147 = 55200
  • 73 + 55127 = 55200
  • 83 + 55117 = 55200
  • 97 + 55103 = 55200
  • 127 + 55073 = 55200
  • 139 + 55061 = 55200

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 55200 first appears in π at position 185,520 of the decimal expansion (the 185,520ordinal-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.
