Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8626668, here are decompositions:

  • 47 + 8626621 = 8626668
  • 139 + 8626529 = 8626668
  • 151 + 8626517 = 8626668
  • 181 + 8626487 = 8626668
  • 199 + 8626469 = 8626668
  • 251 + 8626417 = 8626668
  • 277 + 8626391 = 8626668
  • 367 + 8626301 = 8626668

Showing the first eight; more decompositions exist.
