Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601760, here are decompositions:

17 + 31601743 = 31601760
37 + 31601723 = 31601760
53 + 31601707 = 31601760
61 + 31601699 = 31601760
89 + 31601671 = 31601760
109 + 31601651 = 31601760
131 + 31601629 = 31601760
191 + 31601569 = 31601760

Showing the first eight; more decompositions exist.
