Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294978432, here are decompositions:

  • 71 + 4294978361 = 4294978432
  • 149 + 4294978283 = 4294978432
  • 263 + 4294978169 = 4294978432
  • 443 + 4294977989 = 4294978432
  • 593 + 4294977839 = 4294978432
  • 761 + 4294977671 = 4294978432
  • 809 + 4294977623 = 4294978432
  • 929 + 4294977503 = 4294978432

Showing the first eight; more decompositions exist.
