Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294976638, here are decompositions:

  • 11 + 4294976627 = 4294976638
  • 59 + 4294976579 = 4294976638
  • 89 + 4294976549 = 4294976638
  • 101 + 4294976537 = 4294976638
  • 137 + 4294976501 = 4294976638
  • 191 + 4294976447 = 4294976638
  • 257 + 4294976381 = 4294976638
  • 317 + 4294976321 = 4294976638

Showing the first eight; more decompositions exist.
