Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 157056, here are decompositions:

5 + 157051 = 157056
7 + 157049 = 157056
19 + 157037 = 157056
37 + 157019 = 157056
43 + 157013 = 157056
89 + 156967 = 157056
113 + 156943 = 157056
157 + 156899 = 157056

Showing the first eight; more decompositions exist.
