Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 157218, here are decompositions:

7 + 157211 = 157218
11 + 157207 = 157218
29 + 157189 = 157218
37 + 157181 = 157218
41 + 157177 = 157218
109 + 157109 = 157218
137 + 157081 = 157218
157 + 157061 = 157218

Showing the first eight; more decompositions exist.
