Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72030, here are decompositions:

  • 11 + 72019 = 72030
  • 31 + 71999 = 72030
  • 37 + 71993 = 72030
  • 43 + 71987 = 72030
  • 47 + 71983 = 72030
  • 59 + 71971 = 72030
  • 67 + 71963 = 72030
  • 83 + 71947 = 72030

Showing the first eight; more decompositions exist.
