Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539746, here are decompositions:

  • 19 + 31539727 = 31539746
  • 97 + 31539649 = 31539746
  • 103 + 31539643 = 31539746
  • 163 + 31539583 = 31539746
  • 223 + 31539523 = 31539746
  • 307 + 31539439 = 31539746
  • 379 + 31539367 = 31539746
  • 397 + 31539349 = 31539746

Showing the first eight; more decompositions exist.
