Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620670, here are decompositions:

  • 7 + 8620663 = 8620670
  • 31 + 8620639 = 8620670
  • 67 + 8620603 = 8620670
  • 103 + 8620567 = 8620670
  • 127 + 8620543 = 8620670
  • 241 + 8620429 = 8620670
  • 277 + 8620393 = 8620670
  • 439 + 8620231 = 8620670

Showing the first eight; more decompositions exist.
