Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8689490, here are decompositions:

  • 37 + 8689453 = 8689490
  • 181 + 8689309 = 8689490
  • 211 + 8689279 = 8689490
  • 241 + 8689249 = 8689490
  • 349 + 8689141 = 8689490
  • 379 + 8689111 = 8689490
  • 421 + 8689069 = 8689490
  • 457 + 8689033 = 8689490

Showing the first eight; more decompositions exist.
