Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601906, here are decompositions:

43 + 31601863 = 31601906
97 + 31601809 = 31601906
139 + 31601767 = 31601906
163 + 31601743 = 31601906
199 + 31601707 = 31601906
277 + 31601629 = 31601906
337 + 31601569 = 31601906
367 + 31601539 = 31601906

Showing the first eight; more decompositions exist.
