Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 157002, here are decompositions:

23 + 156979 = 157002
31 + 156971 = 157002
59 + 156943 = 157002
61 + 156941 = 157002
89 + 156913 = 157002
101 + 156901 = 157002
103 + 156899 = 157002
179 + 156823 = 157002

Showing the first eight; more decompositions exist.
