Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72646, here are decompositions:

  • 3 + 72643 = 72646
  • 23 + 72623 = 72646
  • 29 + 72617 = 72646
  • 113 + 72533 = 72646
  • 149 + 72497 = 72646
  • 179 + 72467 = 72646
  • 263 + 72383 = 72646
  • 293 + 72353 = 72646

Showing the first eight; more decompositions exist.
