Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 156716, here are decompositions:

13 + 156703 = 156716
37 + 156679 = 156716
97 + 156619 = 156716
127 + 156589 = 156716
139 + 156577 = 156716
223 + 156493 = 156716
229 + 156487 = 156716
397 + 156319 = 156716

Showing the first eight; more decompositions exist.
