Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 524720, here are decompositions:

13 + 524707 = 524720
19 + 524701 = 524720
37 + 524683 = 524720
127 + 524593 = 524720
199 + 524521 = 524720
211 + 524509 = 524720
223 + 524497 = 524720
307 + 524413 = 524720

Showing the first eight; more decompositions exist.
