Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601652, here are decompositions:

23 + 31601629 = 31601652
83 + 31601569 = 31601652
101 + 31601551 = 31601652
113 + 31601539 = 31601652
139 + 31601513 = 31601652
163 + 31601489 = 31601652
179 + 31601473 = 31601652
241 + 31601411 = 31601652

Showing the first eight; more decompositions exist.
