Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77790, here are decompositions:

  • 7 + 77783 = 77790
  • 17 + 77773 = 77790
  • 29 + 77761 = 77790
  • 43 + 77747 = 77790
  • 47 + 77743 = 77790
  • 59 + 77731 = 77790
  • 67 + 77723 = 77790
  • 71 + 77719 = 77790

Showing the first eight; more decompositions exist.
