Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19120, here are decompositions:

  • 41 + 19079 = 19120
  • 47 + 19073 = 19120
  • 83 + 19037 = 19120
  • 89 + 19031 = 19120
  • 107 + 19013 = 19120
  • 173 + 18947 = 19120
  • 251 + 18869 = 19120
  • 281 + 18839 = 19120

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 19120 first appears in π at position 185,497 of the decimal expansion (the 185,497ordinal-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.
