Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294992420, here are decompositions:

  • 7 + 4294992413 = 4294992420
  • 79 + 4294992341 = 4294992420
  • 109 + 4294992311 = 4294992420
  • 179 + 4294992241 = 4294992420
  • 197 + 4294992223 = 4294992420
  • 223 + 4294992197 = 4294992420
  • 269 + 4294992151 = 4294992420
  • 281 + 4294992139 = 4294992420

Showing the first eight; more decompositions exist.
