Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511636, here are decompositions:

3 + 511633 = 511636
5 + 511631 = 511636
53 + 511583 = 511636
113 + 511523 = 511636
149 + 511487 = 511636
173 + 511463 = 511636
179 + 511457 = 511636
197 + 511439 = 511636

Showing the first eight; more decompositions exist.
