Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8702690, here are decompositions:

  • 43 + 8702647 = 8702690
  • 97 + 8702593 = 8702690
  • 103 + 8702587 = 8702690
  • 151 + 8702539 = 8702690
  • 193 + 8702497 = 8702690
  • 331 + 8702359 = 8702690
  • 349 + 8702341 = 8702690
  • 379 + 8702311 = 8702690

Showing the first eight; more decompositions exist.
