Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64646, here are decompositions:

  • 13 + 64633 = 64646
  • 19 + 64627 = 64646
  • 37 + 64609 = 64646
  • 67 + 64579 = 64646
  • 79 + 64567 = 64646
  • 157 + 64489 = 64646
  • 163 + 64483 = 64646
  • 193 + 64453 = 64646

Showing the first eight; more decompositions exist.
