Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294987240, here are decompositions:

  • 83 + 4294987157 = 4294987240
  • 179 + 4294987061 = 4294987240
  • 251 + 4294986989 = 4294987240
  • 281 + 4294986959 = 4294987240
  • 347 + 4294986893 = 4294987240
  • 389 + 4294986851 = 4294987240
  • 503 + 4294986737 = 4294987240
  • 743 + 4294986497 = 4294987240

Showing the first eight; more decompositions exist.
