Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 510386, here are decompositions:

3 + 510383 = 510386
7 + 510379 = 510386
67 + 510319 = 510386
139 + 510247 = 510386
229 + 510157 = 510386
307 + 510079 = 510386
313 + 510073 = 510386
337 + 510049 = 510386

Showing the first eight; more decompositions exist.
