Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10198, here are decompositions:

  • 5 + 10193 = 10198
  • 17 + 10181 = 10198
  • 29 + 10169 = 10198
  • 47 + 10151 = 10198
  • 59 + 10139 = 10198
  • 107 + 10091 = 10198
  • 131 + 10067 = 10198
  • 137 + 10061 = 10198

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 10198 first appears in π at position 20,430 of the decimal expansion (the 20,430ordinal-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.
