Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294999640, here are decompositions:

  • 103 + 4294999537 = 4294999640
  • 157 + 4294999483 = 4294999640
  • 163 + 4294999477 = 4294999640
  • 277 + 4294999363 = 4294999640
  • 307 + 4294999333 = 4294999640
  • 313 + 4294999327 = 4294999640
  • 433 + 4294999207 = 4294999640
  • 523 + 4294999117 = 4294999640

Showing the first eight; more decompositions exist.
