Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 512618, here are decompositions:

37 + 512581 = 512618
97 + 512521 = 512618
151 + 512467 = 512618
199 + 512419 = 512618
229 + 512389 = 512618
307 + 512311 = 512618
331 + 512287 = 512618
349 + 512269 = 512618

Showing the first eight; more decompositions exist.
