Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601796, here are decompositions:

13 + 31601783 = 31601796
29 + 31601767 = 31601796
53 + 31601743 = 31601796
73 + 31601723 = 31601796
89 + 31601707 = 31601796
97 + 31601699 = 31601796
167 + 31601629 = 31601796
227 + 31601569 = 31601796

Showing the first eight; more decompositions exist.
