Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 523550, here are decompositions:

7 + 523543 = 523550
31 + 523519 = 523550
61 + 523489 = 523550
163 + 523387 = 523550
193 + 523357 = 523550
199 + 523351 = 523550
331 + 523219 = 523550
337 + 523213 = 523550

Showing the first eight; more decompositions exist.
