Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601802, here are decompositions:

19 + 31601783 = 31601802
59 + 31601743 = 31601802
79 + 31601723 = 31601802
103 + 31601699 = 31601802
131 + 31601671 = 31601802
151 + 31601651 = 31601802
173 + 31601629 = 31601802
233 + 31601569 = 31601802

Showing the first eight; more decompositions exist.
