Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11178, here are decompositions:

  • 5 + 11173 = 11178
  • 7 + 11171 = 11178
  • 17 + 11161 = 11178
  • 19 + 11159 = 11178
  • 29 + 11149 = 11178
  • 47 + 11131 = 11178
  • 59 + 11119 = 11178
  • 61 + 11117 = 11178

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 11178 first appears in π at position 127,064 of the decimal expansion (the 127,064ordinal-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.
