Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294978656, here are decompositions:

  • 29 + 4294978627 = 4294978656
  • 97 + 4294978559 = 4294978656
  • 103 + 4294978553 = 4294978656
  • 139 + 4294978517 = 4294978656
  • 167 + 4294978489 = 4294978656
  • 257 + 4294978399 = 4294978656
  • 347 + 4294978309 = 4294978656
  • 349 + 4294978307 = 4294978656

Showing the first eight; more decompositions exist.
