Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601922, here are decompositions:

31 + 31601891 = 31601922
41 + 31601881 = 31601922
59 + 31601863 = 31601922
73 + 31601849 = 31601922
103 + 31601819 = 31601922
113 + 31601809 = 31601922
139 + 31601783 = 31601922
179 + 31601743 = 31601922

Showing the first eight; more decompositions exist.
