Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513908, here are decompositions:

37 + 513871 = 513908
67 + 513841 = 513908
79 + 513829 = 513908
127 + 513781 = 513908
139 + 513769 = 513908
181 + 513727 = 513908
211 + 513697 = 513908
229 + 513679 = 513908

Showing the first eight; more decompositions exist.
