Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561604, here are decompositions:

5 + 561599 = 561604
53 + 561551 = 561604
83 + 561521 = 561604
227 + 561377 = 561604
257 + 561347 = 561604
353 + 561251 = 561604
431 + 561173 = 561604
443 + 561161 = 561604

Showing the first eight; more decompositions exist.
