Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31450982, here are decompositions:

  • 103 + 31450879 = 31450982
  • 139 + 31450843 = 31450982
  • 181 + 31450801 = 31450982
  • 193 + 31450789 = 31450982
  • 379 + 31450603 = 31450982
  • 439 + 31450543 = 31450982
  • 499 + 31450483 = 31450982
  • 571 + 31450411 = 31450982

Showing the first eight; more decompositions exist.
