Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19006, here are decompositions:

  • 5 + 19001 = 19006
  • 47 + 18959 = 19006
  • 59 + 18947 = 19006
  • 89 + 18917 = 19006
  • 107 + 18899 = 19006
  • 137 + 18869 = 19006
  • 167 + 18839 = 19006
  • 233 + 18773 = 19006

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 19006 first appears in π at position 71,921 of the decimal expansion (the 71,921ordinal-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.
