Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601676, here are decompositions:

5 + 31601671 = 31601676
47 + 31601629 = 31601676
107 + 31601569 = 31601676
109 + 31601567 = 31601676
137 + 31601539 = 31601676
149 + 31601527 = 31601676
163 + 31601513 = 31601676
167 + 31601509 = 31601676

Showing the first eight; more decompositions exist.
