Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8636290, here are decompositions:

  • 29 + 8636261 = 8636290
  • 53 + 8636237 = 8636290
  • 71 + 8636219 = 8636290
  • 149 + 8636141 = 8636290
  • 167 + 8636123 = 8636290
  • 197 + 8636093 = 8636290
  • 233 + 8636057 = 8636290
  • 251 + 8636039 = 8636290

Showing the first eight; more decompositions exist.
