Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 512494, here are decompositions:

173 + 512321 = 512494
347 + 512147 = 512494
401 + 512093 = 512494
503 + 511991 = 512494
683 + 511811 = 512494
701 + 511793 = 512494
863 + 511631 = 512494
911 + 511583 = 512494

Showing the first eight; more decompositions exist.
