Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 169982, here are decompositions:

31 + 169951 = 169982
73 + 169909 = 169982
139 + 169843 = 169982
151 + 169831 = 169982
193 + 169789 = 169982
199 + 169783 = 169982
229 + 169753 = 169982
349 + 169633 = 169982

Showing the first eight; more decompositions exist.
