Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 506646, here are decompositions:

17 + 506629 = 506646
37 + 506609 = 506646
47 + 506599 = 506646
53 + 506593 = 506646
73 + 506573 = 506646
83 + 506563 = 506646
109 + 506537 = 506646
113 + 506533 = 506646

Showing the first eight; more decompositions exist.
