Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 74728, here are decompositions:

  • 11 + 74717 = 74728
  • 29 + 74699 = 74728
  • 41 + 74687 = 74728
  • 131 + 74597 = 74728
  • 167 + 74561 = 74728
  • 197 + 74531 = 74728
  • 239 + 74489 = 74728
  • 257 + 74471 = 74728

Showing the first eight; more decompositions exist.
