Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8609438, here are decompositions:

  • 7 + 8609431 = 8609438
  • 67 + 8609371 = 8609438
  • 151 + 8609287 = 8609438
  • 157 + 8609281 = 8609438
  • 181 + 8609257 = 8609438
  • 199 + 8609239 = 8609438
  • 547 + 8608891 = 8609438
  • 577 + 8608861 = 8609438

Showing the first eight; more decompositions exist.
