Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601844, here are decompositions:

7 + 31601837 = 31601844
61 + 31601783 = 31601844
101 + 31601743 = 31601844
137 + 31601707 = 31601844
173 + 31601671 = 31601844
193 + 31601651 = 31601844
277 + 31601567 = 31601844
293 + 31601551 = 31601844

Showing the first eight; more decompositions exist.
