Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601832, here are decompositions:

13 + 31601819 = 31601832
23 + 31601809 = 31601832
89 + 31601743 = 31601832
109 + 31601723 = 31601832
181 + 31601651 = 31601832
263 + 31601569 = 31601832
281 + 31601551 = 31601832
293 + 31601539 = 31601832

Showing the first eight; more decompositions exist.
