Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513926, here are decompositions:

3 + 513923 = 513926
97 + 513829 = 513926
157 + 513769 = 513926
199 + 513727 = 513926
229 + 513697 = 513926
277 + 513649 = 513926
397 + 513529 = 513926
487 + 513439 = 513926

Showing the first eight; more decompositions exist.
