Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31486268, here are decompositions:

  • 67 + 31486201 = 31486268
  • 139 + 31486129 = 31486268
  • 181 + 31486087 = 31486268
  • 337 + 31485931 = 31486268
  • 379 + 31485889 = 31486268
  • 397 + 31485871 = 31486268
  • 547 + 31485721 = 31486268
  • 607 + 31485661 = 31486268

Showing the first eight; more decompositions exist.
