Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294978242, here are decompositions:

  • 11 + 4294978231 = 4294978242
  • 19 + 4294978223 = 4294978242
  • 31 + 4294978211 = 4294978242
  • 41 + 4294978201 = 4294978242
  • 73 + 4294978169 = 4294978242
  • 109 + 4294978133 = 4294978242
  • 151 + 4294978091 = 4294978242
  • 239 + 4294978003 = 4294978242

Showing the first eight; more decompositions exist.
