Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11528, here are decompositions:

  • 31 + 11497 = 11528
  • 37 + 11491 = 11528
  • 61 + 11467 = 11528
  • 199 + 11329 = 11528
  • 211 + 11317 = 11528
  • 229 + 11299 = 11528
  • 241 + 11287 = 11528
  • 271 + 11257 = 11528

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 11528 first appears in π at position 7,434 of the decimal expansion (the 7,434ordinal-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.
