Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 156956, here are decompositions:

13 + 156943 = 156956
43 + 156913 = 156956
139 + 156817 = 156956
157 + 156799 = 156956
223 + 156733 = 156956
229 + 156727 = 156956
277 + 156679 = 156956
337 + 156619 = 156956

Showing the first eight; more decompositions exist.
