Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622290, here are decompositions:

  • 3 + 8622287 = 8622290
  • 67 + 8622223 = 8622290
  • 163 + 8622127 = 8622290
  • 283 + 8622007 = 8622290
  • 307 + 8621983 = 8622290
  • 331 + 8621959 = 8622290
  • 379 + 8621911 = 8622290
  • 421 + 8621869 = 8622290

Showing the first eight; more decompositions exist.
