Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294978742, here are decompositions:

  • 13 + 4294978729 = 4294978742
  • 151 + 4294978591 = 4294978742
  • 409 + 4294978333 = 4294978742
  • 433 + 4294978309 = 4294978742
  • 541 + 4294978201 = 4294978742
  • 619 + 4294978123 = 4294978742
  • 661 + 4294978081 = 4294978742
  • 709 + 4294978033 = 4294978742

Showing the first eight; more decompositions exist.
