Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 512186, here are decompositions:

19 + 512167 = 512186
127 + 512059 = 512186
139 + 512047 = 512186
223 + 511963 = 512186
277 + 511909 = 512186
313 + 511873 = 512186
463 + 511723 = 512186
607 + 511579 = 512186

Showing the first eight; more decompositions exist.
