Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10018, here are decompositions:

  • 11 + 10007 = 10018
  • 89 + 9929 = 10018
  • 131 + 9887 = 10018
  • 167 + 9851 = 10018
  • 179 + 9839 = 10018
  • 227 + 9791 = 10018
  • 251 + 9767 = 10018
  • 269 + 9749 = 10018

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 10018 first appears in π at position 31,833 of the decimal expansion (the 31,833ordinal-suffix:rd 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.
