Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11288, here are decompositions:

  • 31 + 11257 = 11288
  • 37 + 11251 = 11288
  • 127 + 11161 = 11288
  • 139 + 11149 = 11288
  • 157 + 11131 = 11288
  • 229 + 11059 = 11288
  • 241 + 11047 = 11288
  • 331 + 10957 = 11288

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 11288 first appears in π at position 20,334 of the decimal expansion (the 20,334ordinal-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.
