Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531358, here are decompositions:

5 + 531353 = 531358
11 + 531347 = 531358
59 + 531299 = 531358
71 + 531287 = 531358
257 + 531101 = 531358
389 + 530969 = 531358
461 + 530897 = 531358
521 + 530837 = 531358

Showing the first eight; more decompositions exist.
