Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294977768, here are decompositions:

  • 5 + 4294977763 = 4294977768
  • 7 + 4294977761 = 4294977768
  • 17 + 4294977751 = 4294977768
  • 97 + 4294977671 = 4294977768
  • 101 + 4294977667 = 4294977768
  • 197 + 4294977571 = 4294977768
  • 269 + 4294977499 = 4294977768
  • 337 + 4294977431 = 4294977768

Showing the first eight; more decompositions exist.
