Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294978828, here are decompositions:

  • 17 + 4294978811 = 4294978828
  • 29 + 4294978799 = 4294978828
  • 47 + 4294978781 = 4294978828
  • 71 + 4294978757 = 4294978828
  • 149 + 4294978679 = 4294978828
  • 167 + 4294978661 = 4294978828
  • 269 + 4294978559 = 4294978828
  • 311 + 4294978517 = 4294978828

Showing the first eight; more decompositions exist.
