Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294976642, here are decompositions:

  • 3 + 4294976639 = 4294976642
  • 211 + 4294976431 = 4294976642
  • 283 + 4294976359 = 4294976642
  • 331 + 4294976311 = 4294976642
  • 349 + 4294976293 = 4294976642
  • 373 + 4294976269 = 4294976642
  • 379 + 4294976263 = 4294976642
  • 421 + 4294976221 = 4294976642

Showing the first eight; more decompositions exist.
