Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294992642, here are decompositions:

  • 179 + 4294992463 = 4294992642
  • 229 + 4294992413 = 4294992642
  • 331 + 4294992311 = 4294992642
  • 401 + 4294992241 = 4294992642
  • 419 + 4294992223 = 4294992642
  • 439 + 4294992203 = 4294992642
  • 491 + 4294992151 = 4294992642
  • 503 + 4294992139 = 4294992642

Showing the first eight; more decompositions exist.
