Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518148, here are decompositions:

11 + 518137 = 518148
17 + 518131 = 518148
19 + 518129 = 518148
47 + 518101 = 518148
89 + 518059 = 518148
101 + 518047 = 518148
131 + 518017 = 518148
149 + 517999 = 518148

Showing the first eight; more decompositions exist.
