Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601622, here are decompositions:

53 + 31601569 = 31601622
71 + 31601551 = 31601622
83 + 31601539 = 31601622
109 + 31601513 = 31601622
113 + 31601509 = 31601622
149 + 31601473 = 31601622
211 + 31601411 = 31601622
229 + 31601393 = 31601622

Showing the first eight; more decompositions exist.
