Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 510786, here are decompositions:

13 + 510773 = 510786
19 + 510767 = 510786
79 + 510707 = 510786
103 + 510683 = 510786
109 + 510677 = 510786
167 + 510619 = 510786
173 + 510613 = 510786
197 + 510589 = 510786

Showing the first eight; more decompositions exist.
