Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294977820, here are decompositions:

  • 59 + 4294977761 = 4294977820
  • 149 + 4294977671 = 4294977820
  • 197 + 4294977623 = 4294977820
  • 317 + 4294977503 = 4294977820
  • 389 + 4294977431 = 4294977820
  • 401 + 4294977419 = 4294977820
  • 431 + 4294977389 = 4294977820
  • 491 + 4294977329 = 4294977820

Showing the first eight; more decompositions exist.
