Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601576, here are decompositions:

7 + 31601569 = 31601576
37 + 31601539 = 31601576
67 + 31601509 = 31601576
103 + 31601473 = 31601576
229 + 31601347 = 31601576
313 + 31601263 = 31601576
373 + 31601203 = 31601576
397 + 31601179 = 31601576

Showing the first eight; more decompositions exist.
