Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601670, here are decompositions:

19 + 31601651 = 31601670
41 + 31601629 = 31601670
101 + 31601569 = 31601670
103 + 31601567 = 31601670
131 + 31601539 = 31601670
157 + 31601513 = 31601670
181 + 31601489 = 31601670
197 + 31601473 = 31601670

Showing the first eight; more decompositions exist.
