Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294987512, here are decompositions:

  • 181 + 4294987331 = 4294987512
  • 223 + 4294987289 = 4294987512
  • 281 + 4294987231 = 4294987512
  • 401 + 4294987111 = 4294987512
  • 461 + 4294987051 = 4294987512
  • 521 + 4294986991 = 4294987512
  • 523 + 4294986989 = 4294987512
  • 601 + 4294986911 = 4294987512

Showing the first eight; more decompositions exist.
