Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294978864, here are decompositions:

  • 53 + 4294978811 = 4294978864
  • 83 + 4294978781 = 4294978864
  • 107 + 4294978757 = 4294978864
  • 131 + 4294978733 = 4294978864
  • 311 + 4294978553 = 4294978864
  • 347 + 4294978517 = 4294978864
  • 353 + 4294978511 = 4294978864
  • 503 + 4294978361 = 4294978864

Showing the first eight; more decompositions exist.
