Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 524518, here are decompositions:

11 + 524507 = 524518
89 + 524429 = 524518
107 + 524411 = 524518
131 + 524387 = 524518
149 + 524369 = 524518
167 + 524351 = 524518
257 + 524261 = 524518
317 + 524201 = 524518

Showing the first eight; more decompositions exist.
