Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77646, here are decompositions:

  • 5 + 77641 = 77646
  • 29 + 77617 = 77646
  • 59 + 77587 = 77646
  • 73 + 77573 = 77646
  • 83 + 77563 = 77646
  • 89 + 77557 = 77646
  • 97 + 77549 = 77646
  • 103 + 77543 = 77646

Showing the first eight; more decompositions exist.
