Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77644, here are decompositions:

  • 3 + 77641 = 77644
  • 23 + 77621 = 77644
  • 53 + 77591 = 77644
  • 71 + 77573 = 77644
  • 101 + 77543 = 77644
  • 131 + 77513 = 77644
  • 167 + 77477 = 77644
  • 173 + 77471 = 77644

Showing the first eight; more decompositions exist.
