Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601592, here are decompositions:

23 + 31601569 = 31601592
41 + 31601551 = 31601592
53 + 31601539 = 31601592
79 + 31601513 = 31601592
83 + 31601509 = 31601592
103 + 31601489 = 31601592
181 + 31601411 = 31601592
199 + 31601393 = 31601592

Showing the first eight; more decompositions exist.
