Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77478, here are decompositions:

  • 7 + 77471 = 77478
  • 31 + 77447 = 77478
  • 47 + 77431 = 77478
  • 59 + 77419 = 77478
  • 61 + 77417 = 77478
  • 101 + 77377 = 77478
  • 109 + 77369 = 77478
  • 127 + 77351 = 77478

Showing the first eight; more decompositions exist.
