Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294987312, here are decompositions:

  • 23 + 4294987289 = 4294987312
  • 251 + 4294987061 = 4294987312
  • 353 + 4294986959 = 4294987312
  • 359 + 4294986953 = 4294987312
  • 401 + 4294986911 = 4294987312
  • 419 + 4294986893 = 4294987312
  • 449 + 4294986863 = 4294987312
  • 461 + 4294986851 = 4294987312

Showing the first eight; more decompositions exist.
