Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601822, here are decompositions:

3 + 31601819 = 31601822
13 + 31601809 = 31601822
79 + 31601743 = 31601822
151 + 31601671 = 31601822
193 + 31601629 = 31601822
271 + 31601551 = 31601822
283 + 31601539 = 31601822
313 + 31601509 = 31601822

Showing the first eight; more decompositions exist.
