Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 512216, here are decompositions:

79 + 512137 = 512216
157 + 512059 = 512216
277 + 511939 = 512216
283 + 511933 = 512216
307 + 511909 = 512216
349 + 511867 = 512216
373 + 511843 = 512216
547 + 511669 = 512216

Showing the first eight; more decompositions exist.
