Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 512386, here are decompositions:

53 + 512333 = 512386
137 + 512249 = 512386
179 + 512207 = 512386
239 + 512147 = 512386
293 + 512093 = 512386
389 + 511997 = 512386
593 + 511793 = 512386
599 + 511787 = 512386

Showing the first eight; more decompositions exist.
