Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738742, here are decompositions:

  • 13 + 8738729 = 8738742
  • 29 + 8738713 = 8738742
  • 31 + 8738711 = 8738742
  • 71 + 8738671 = 8738742
  • 83 + 8738659 = 8738742
  • 101 + 8738641 = 8738742
  • 151 + 8738591 = 8738742
  • 163 + 8738579 = 8738742

Showing the first eight; more decompositions exist.
