Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601826, here are decompositions:

7 + 31601819 = 31601826
17 + 31601809 = 31601826
43 + 31601783 = 31601826
59 + 31601767 = 31601826
83 + 31601743 = 31601826
103 + 31601723 = 31601826
127 + 31601699 = 31601826
197 + 31601629 = 31601826

Showing the first eight; more decompositions exist.
