Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27100, here are decompositions:

  • 23 + 27077 = 27100
  • 41 + 27059 = 27100
  • 83 + 27017 = 27100
  • 89 + 27011 = 27100
  • 107 + 26993 = 27100
  • 113 + 26987 = 27100
  • 149 + 26951 = 27100
  • 173 + 26927 = 27100

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 27100 first appears in π at position 45,179 of the decimal expansion (the 45,179ordinal-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.
