Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601358, here are decompositions:

11 + 31601347 = 31601358
17 + 31601341 = 31601358
167 + 31601191 = 31601358
179 + 31601179 = 31601358
281 + 31601077 = 31601358
307 + 31601051 = 31601358
317 + 31601041 = 31601358
389 + 31600969 = 31601358

Showing the first eight; more decompositions exist.
