Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8609090, here are decompositions:

  • 3 + 8609087 = 8609090
  • 13 + 8609077 = 8609090
  • 67 + 8609023 = 8609090
  • 181 + 8608909 = 8609090
  • 199 + 8608891 = 8609090
  • 211 + 8608879 = 8609090
  • 229 + 8608861 = 8609090
  • 313 + 8608777 = 8609090

Showing the first eight; more decompositions exist.
