Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294977778, here are decompositions:

  • 17 + 4294977761 = 4294977778
  • 107 + 4294977671 = 4294977778
  • 347 + 4294977431 = 4294977778
  • 359 + 4294977419 = 4294977778
  • 389 + 4294977389 = 4294977778
  • 431 + 4294977347 = 4294977778
  • 449 + 4294977329 = 4294977778
  • 461 + 4294977317 = 4294977778

Showing the first eight; more decompositions exist.
