Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 517646, here are decompositions:

7 + 517639 = 517646
37 + 517609 = 517646
43 + 517603 = 517646
97 + 517549 = 517646
139 + 517507 = 517646
229 + 517417 = 517646
379 + 517267 = 517646
397 + 517249 = 517646

Showing the first eight; more decompositions exist.
