Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294978520, here are decompositions:

  • 3 + 4294978517 = 4294978520
  • 31 + 4294978489 = 4294978520
  • 139 + 4294978381 = 4294978520
  • 193 + 4294978327 = 4294978520
  • 211 + 4294978309 = 4294978520
  • 271 + 4294978249 = 4294978520
  • 373 + 4294978147 = 4294978520
  • 397 + 4294978123 = 4294978520

Showing the first eight; more decompositions exist.
