Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55810, here are decompositions:

  • 3 + 55807 = 55810
  • 11 + 55799 = 55810
  • 17 + 55793 = 55810
  • 23 + 55787 = 55810
  • 47 + 55763 = 55810
  • 89 + 55721 = 55810
  • 113 + 55697 = 55810
  • 137 + 55673 = 55810

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 55810 first appears in π at position 4,072 of the decimal expansion (the 4,072ordinal-suffix:nd 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.
