Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294987422, here are decompositions:

  • 29 + 4294987393 = 4294987422
  • 191 + 4294987231 = 4294987422
  • 281 + 4294987141 = 4294987422
  • 311 + 4294987111 = 4294987422
  • 431 + 4294986991 = 4294987422
  • 433 + 4294986989 = 4294987422
  • 463 + 4294986959 = 4294987422
  • 571 + 4294986851 = 4294987422

Showing the first eight; more decompositions exist.
