Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42784, here are decompositions:

  • 11 + 42773 = 42784
  • 17 + 42767 = 42784
  • 41 + 42743 = 42784
  • 47 + 42737 = 42784
  • 83 + 42701 = 42784
  • 101 + 42683 = 42784
  • 107 + 42677 = 42784
  • 173 + 42611 = 42784

Showing the first eight; more decompositions exist.
