Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601982, here are decompositions:

59 + 31601923 = 31601982
101 + 31601881 = 31601982
109 + 31601873 = 31601982
163 + 31601819 = 31601982
173 + 31601809 = 31601982
199 + 31601783 = 31601982
239 + 31601743 = 31601982
271 + 31601711 = 31601982

Showing the first eight; more decompositions exist.
