Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601552, here are decompositions:

13 + 31601539 = 31601552
43 + 31601509 = 31601552
79 + 31601473 = 31601552
193 + 31601359 = 31601552
211 + 31601341 = 31601552
349 + 31601203 = 31601552
373 + 31601179 = 31601552
691 + 31600861 = 31601552

Showing the first eight; more decompositions exist.
