Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540502, here are decompositions:

  • 3 + 31540499 = 31540502
  • 13 + 31540489 = 31540502
  • 31 + 31540471 = 31540502
  • 61 + 31540441 = 31540502
  • 139 + 31540363 = 31540502
  • 163 + 31540339 = 31540502
  • 193 + 31540309 = 31540502
  • 241 + 31540261 = 31540502

Showing the first eight; more decompositions exist.
