Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294992920, here are decompositions:

  • 7 + 4294992913 = 4294992920
  • 79 + 4294992841 = 4294992920
  • 277 + 4294992643 = 4294992920
  • 373 + 4294992547 = 4294992920
  • 457 + 4294992463 = 4294992920
  • 577 + 4294992343 = 4294992920
  • 769 + 4294992151 = 4294992920
  • 919 + 4294992001 = 4294992920

Showing the first eight; more decompositions exist.
