Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622190, here are decompositions:

  • 53 + 8622137 = 8622190
  • 149 + 8622041 = 8622190
  • 167 + 8622023 = 8622190
  • 173 + 8622017 = 8622190
  • 179 + 8622011 = 8622190
  • 251 + 8621939 = 8622190
  • 257 + 8621933 = 8622190
  • 263 + 8621927 = 8622190

Showing the first eight; more decompositions exist.
