Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294978972, here are decompositions:

  • 23 + 4294978949 = 4294978972
  • 173 + 4294978799 = 4294978972
  • 191 + 4294978781 = 4294978972
  • 239 + 4294978733 = 4294978972
  • 293 + 4294978679 = 4294978972
  • 311 + 4294978661 = 4294978972
  • 419 + 4294978553 = 4294978972
  • 461 + 4294978511 = 4294978972

Showing the first eight; more decompositions exist.
