Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515922, here are decompositions:

5 + 515917 = 515922
61 + 515861 = 515922
79 + 515843 = 515922
83 + 515839 = 515922
109 + 515813 = 515922
139 + 515783 = 515922
149 + 515773 = 515922
151 + 515771 = 515922

Showing the first eight; more decompositions exist.
