Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521524, here are decompositions:

5 + 521519 = 521524
41 + 521483 = 521524
53 + 521471 = 521524
131 + 521393 = 521524
167 + 521357 = 521524
257 + 521267 = 521524
281 + 521243 = 521524
293 + 521231 = 521524

Showing the first eight; more decompositions exist.
