Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42688, here are decompositions:

  • 5 + 42683 = 42688
  • 11 + 42677 = 42688
  • 47 + 42641 = 42688
  • 131 + 42557 = 42688
  • 179 + 42509 = 42688
  • 197 + 42491 = 42688
  • 227 + 42461 = 42688
  • 251 + 42437 = 42688

Showing the first eight; more decompositions exist.
