Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601526, here are decompositions:

13 + 31601513 = 31601526
17 + 31601509 = 31601526
37 + 31601489 = 31601526
53 + 31601473 = 31601526
109 + 31601417 = 31601526
167 + 31601359 = 31601526
179 + 31601347 = 31601526
263 + 31601263 = 31601526

Showing the first eight; more decompositions exist.
