Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 517380, here are decompositions:

7 + 517373 = 517380
13 + 517367 = 517380
37 + 517343 = 517380
43 + 517337 = 517380
103 + 517277 = 517380
113 + 517267 = 517380
131 + 517249 = 517380
137 + 517243 = 517380

Showing the first eight; more decompositions exist.
