Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294987256, here are decompositions:

  • 199 + 4294987057 = 4294987256
  • 349 + 4294986907 = 4294987256
  • 367 + 4294986889 = 4294987256
  • 463 + 4294986793 = 4294987256
  • 499 + 4294986757 = 4294987256
  • 607 + 4294986649 = 4294987256
  • 613 + 4294986643 = 4294987256
  • 709 + 4294986547 = 4294987256

Showing the first eight; more decompositions exist.
