Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513566, here are decompositions:

37 + 513529 = 513566
127 + 513439 = 513566
139 + 513427 = 513566
199 + 513367 = 513566
283 + 513283 = 513566
397 + 513169 = 513566
409 + 513157 = 513566
457 + 513109 = 513566

Showing the first eight; more decompositions exist.
