Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8674490, here are decompositions:

  • 7 + 8674483 = 8674490
  • 37 + 8674453 = 8674490
  • 43 + 8674447 = 8674490
  • 151 + 8674339 = 8674490
  • 241 + 8674249 = 8674490
  • 277 + 8674213 = 8674490
  • 313 + 8674177 = 8674490
  • 421 + 8674069 = 8674490

Showing the first eight; more decompositions exist.
