Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294978390, here are decompositions:

  • 29 + 4294978361 = 4294978390
  • 83 + 4294978307 = 4294978390
  • 107 + 4294978283 = 4294978390
  • 167 + 4294978223 = 4294978390
  • 179 + 4294978211 = 4294978390
  • 233 + 4294978157 = 4294978390
  • 257 + 4294978133 = 4294978390
  • 401 + 4294977989 = 4294978390

Showing the first eight; more decompositions exist.
