Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294978146, here are decompositions:

  • 13 + 4294978133 = 4294978146
  • 23 + 4294978123 = 4294978146
  • 59 + 4294978087 = 4294978146
  • 79 + 4294978067 = 4294978146
  • 89 + 4294978057 = 4294978146
  • 113 + 4294978033 = 4294978146
  • 157 + 4294977989 = 4294978146
  • 307 + 4294977839 = 4294978146

Showing the first eight; more decompositions exist.
