Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601582, here are decompositions:

13 + 31601569 = 31601582
31 + 31601551 = 31601582
43 + 31601539 = 31601582
73 + 31601509 = 31601582
109 + 31601473 = 31601582
223 + 31601359 = 31601582
241 + 31601341 = 31601582
379 + 31601203 = 31601582

Showing the first eight; more decompositions exist.
