Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622278, here are decompositions:

  • 37 + 8622241 = 8622278
  • 151 + 8622127 = 8622278
  • 271 + 8622007 = 8622278
  • 277 + 8622001 = 8622278
  • 307 + 8621971 = 8622278
  • 331 + 8621947 = 8622278
  • 367 + 8621911 = 8622278
  • 409 + 8621869 = 8622278

Showing the first eight; more decompositions exist.
