Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525418, here are decompositions:

41 + 525377 = 525418
59 + 525359 = 525418
197 + 525221 = 525418
227 + 525191 = 525418
251 + 525167 = 525418
281 + 525137 = 525418
317 + 525101 = 525418
389 + 525029 = 525418

Showing the first eight; more decompositions exist.
