Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11478, here are decompositions:

  • 7 + 11471 = 11478
  • 11 + 11467 = 11478
  • 31 + 11447 = 11478
  • 41 + 11437 = 11478
  • 67 + 11411 = 11478
  • 79 + 11399 = 11478
  • 109 + 11369 = 11478
  • 127 + 11351 = 11478

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 11478 first appears in π at position 272,201 of the decimal expansion (the 272,201ordinal-suffix:st 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.
