Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607882, here are decompositions:

  • 13 + 31607869 = 31607882
  • 43 + 31607839 = 31607882
  • 193 + 31607689 = 31607882
  • 199 + 31607683 = 31607882
  • 211 + 31607671 = 31607882
  • 283 + 31607599 = 31607882
  • 331 + 31607551 = 31607882
  • 379 + 31607503 = 31607882

Showing the first eight; more decompositions exist.
