Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77678, here are decompositions:

  • 19 + 77659 = 77678
  • 31 + 77647 = 77678
  • 37 + 77641 = 77678
  • 61 + 77617 = 77678
  • 67 + 77611 = 77678
  • 109 + 77569 = 77678
  • 127 + 77551 = 77678
  • 151 + 77527 = 77678

Showing the first eight; more decompositions exist.
