Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 512786, here are decompositions:

7 + 512779 = 512786
19 + 512767 = 512786
73 + 512713 = 512786
103 + 512683 = 512786
193 + 512593 = 512786
283 + 512503 = 512786
367 + 512419 = 512786
397 + 512389 = 512786

Showing the first eight; more decompositions exist.
