Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667228, here are decompositions:

  • 61 + 8667167 = 8667228
  • 107 + 8667121 = 8667228
  • 149 + 8667079 = 8667228
  • 239 + 8666989 = 8667228
  • 337 + 8666891 = 8667228
  • 347 + 8666881 = 8667228
  • 379 + 8666849 = 8667228
  • 389 + 8666839 = 8667228

Showing the first eight; more decompositions exist.
