Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 156260, here are decompositions:

3 + 156257 = 156260
7 + 156253 = 156260
19 + 156241 = 156260
31 + 156229 = 156260
43 + 156217 = 156260
103 + 156157 = 156260
109 + 156151 = 156260
151 + 156109 = 156260

Showing the first eight; more decompositions exist.
