Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11822, here are decompositions:

  • 43 + 11779 = 11822
  • 79 + 11743 = 11822
  • 103 + 11719 = 11822
  • 229 + 11593 = 11822
  • 271 + 11551 = 11822
  • 331 + 11491 = 11822
  • 379 + 11443 = 11822
  • 439 + 11383 = 11822

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 11822 first appears in π at position 115,432 of the decimal expansion (the 115,432ordinal-suffix:nd 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.
