Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 156812, here are decompositions:

13 + 156799 = 156812
31 + 156781 = 156812
79 + 156733 = 156812
109 + 156703 = 156812
181 + 156631 = 156812
193 + 156619 = 156812
211 + 156601 = 156812
223 + 156589 = 156812

Showing the first eight; more decompositions exist.
