Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294997878, here are decompositions:

  • 5 + 4294997873 = 4294997878
  • 167 + 4294997711 = 4294997878
  • 191 + 4294997687 = 4294997878
  • 251 + 4294997627 = 4294997878
  • 317 + 4294997561 = 4294997878
  • 461 + 4294997417 = 4294997878
  • 491 + 4294997387 = 4294997878
  • 617 + 4294997261 = 4294997878

Showing the first eight; more decompositions exist.
