Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 67778, here are decompositions:

  • 19 + 67759 = 67778
  • 37 + 67741 = 67778
  • 79 + 67699 = 67778
  • 127 + 67651 = 67778
  • 199 + 67579 = 67778
  • 211 + 67567 = 67778
  • 241 + 67537 = 67778
  • 331 + 67447 = 67778

Showing the first eight; more decompositions exist.
