Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 523556, here are decompositions:

3 + 523553 = 523556
13 + 523543 = 523556
37 + 523519 = 523556
67 + 523489 = 523556
97 + 523459 = 523556
139 + 523417 = 523556
199 + 523357 = 523556
223 + 523333 = 523556

Showing the first eight; more decompositions exist.
