Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518156, here are decompositions:

3 + 518153 = 518156
19 + 518137 = 518156
43 + 518113 = 518156
73 + 518083 = 518156
97 + 518059 = 518156
109 + 518047 = 518156
139 + 518017 = 518156
157 + 517999 = 518156

Showing the first eight; more decompositions exist.
