Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520618, here are decompositions:

11 + 520607 = 520618
29 + 520589 = 520618
47 + 520571 = 520618
71 + 520547 = 520618
89 + 520529 = 520618
167 + 520451 = 520618
191 + 520427 = 520618
239 + 520379 = 520618

Showing the first eight; more decompositions exist.
