Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294999940, here are decompositions:

  • 163 + 4294999777 = 4294999940
  • 199 + 4294999741 = 4294999940
  • 223 + 4294999717 = 4294999940
  • 241 + 4294999699 = 4294999940
  • 457 + 4294999483 = 4294999940
  • 463 + 4294999477 = 4294999940
  • 577 + 4294999363 = 4294999940
  • 601 + 4294999339 = 4294999940

Showing the first eight; more decompositions exist.
