Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 523512, here are decompositions:

19 + 523493 = 523512
23 + 523489 = 523512
53 + 523459 = 523512
79 + 523433 = 523512
109 + 523403 = 523512
163 + 523349 = 523512
179 + 523333 = 523512
251 + 523261 = 523512

Showing the first eight; more decompositions exist.
