Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520690, here are decompositions:

11 + 520679 = 520690
41 + 520649 = 520690
59 + 520631 = 520690
83 + 520607 = 520690
101 + 520589 = 520690
239 + 520451 = 520690
257 + 520433 = 520690
263 + 520427 = 520690

Showing the first eight; more decompositions exist.
