Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294977940, here are decompositions:

  • 41 + 4294977899 = 4294977940
  • 47 + 4294977893 = 4294977940
  • 59 + 4294977881 = 4294977940
  • 101 + 4294977839 = 4294977940
  • 179 + 4294977761 = 4294977940
  • 269 + 4294977671 = 4294977940
  • 317 + 4294977623 = 4294977940
  • 509 + 4294977431 = 4294977940

Showing the first eight; more decompositions exist.
