Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294978340, here are decompositions:

  • 7 + 4294978333 = 4294978340
  • 13 + 4294978327 = 4294978340
  • 31 + 4294978309 = 4294978340
  • 109 + 4294978231 = 4294978340
  • 139 + 4294978201 = 4294978340
  • 193 + 4294978147 = 4294978340
  • 283 + 4294978057 = 4294978340
  • 307 + 4294978033 = 4294978340

Showing the first eight; more decompositions exist.
