Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294978468, here are decompositions:

  • 107 + 4294978361 = 4294978468
  • 257 + 4294978211 = 4294978468
  • 311 + 4294978157 = 4294978468
  • 401 + 4294978067 = 4294978468
  • 479 + 4294977989 = 4294978468
  • 569 + 4294977899 = 4294978468
  • 587 + 4294977881 = 4294978468
  • 797 + 4294977671 = 4294978468

Showing the first eight; more decompositions exist.
