Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294978090, here are decompositions:

  • 3 + 4294978087 = 4294978090
  • 23 + 4294978067 = 4294978090
  • 101 + 4294977989 = 4294978090
  • 191 + 4294977899 = 4294978090
  • 197 + 4294977893 = 4294978090
  • 251 + 4294977839 = 4294978090
  • 419 + 4294977671 = 4294978090
  • 467 + 4294977623 = 4294978090

Showing the first eight; more decompositions exist.
