Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 157020, here are decompositions:

7 + 157013 = 157020
13 + 157007 = 157020
41 + 156979 = 157020
53 + 156967 = 157020
79 + 156941 = 157020
107 + 156913 = 157020
179 + 156841 = 157020
197 + 156823 = 157020

Showing the first eight; more decompositions exist.
