Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 512390, here are decompositions:

37 + 512353 = 512390
79 + 512311 = 512390
103 + 512287 = 512390
139 + 512251 = 512390
223 + 512167 = 512390
331 + 512059 = 512390
379 + 512011 = 512390
457 + 511933 = 512390

Showing the first eight; more decompositions exist.
