Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10288, here are decompositions:

  • 17 + 10271 = 10288
  • 29 + 10259 = 10288
  • 41 + 10247 = 10288
  • 107 + 10181 = 10288
  • 137 + 10151 = 10288
  • 149 + 10139 = 10288
  • 197 + 10091 = 10288
  • 227 + 10061 = 10288

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 10288 first appears in π at position 21,103 of the decimal expansion (the 21,103ordinal-suffix:rd 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.
