Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 524538, here are decompositions:

17 + 524521 = 524538
19 + 524519 = 524538
29 + 524509 = 524538
31 + 524507 = 524538
41 + 524497 = 524538
109 + 524429 = 524538
127 + 524411 = 524538
149 + 524389 = 524538

Showing the first eight; more decompositions exist.
