Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8629820, here are decompositions:

  • 7 + 8629813 = 8629820
  • 109 + 8629711 = 8629820
  • 139 + 8629681 = 8629820
  • 223 + 8629597 = 8629820
  • 313 + 8629507 = 8629820
  • 337 + 8629483 = 8629820
  • 373 + 8629447 = 8629820
  • 379 + 8629441 = 8629820

Showing the first eight; more decompositions exist.
