Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 156650, here are decompositions:

19 + 156631 = 156650
31 + 156619 = 156650
61 + 156589 = 156650
73 + 156577 = 156650
139 + 156511 = 156650
157 + 156493 = 156650
163 + 156487 = 156650
229 + 156421 = 156650

Showing the first eight; more decompositions exist.
