Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601604, here are decompositions:

37 + 31601567 = 31601604
53 + 31601551 = 31601604
131 + 31601473 = 31601604
193 + 31601411 = 31601604
197 + 31601407 = 31601604
211 + 31601393 = 31601604
257 + 31601347 = 31601604
263 + 31601341 = 31601604

Showing the first eight; more decompositions exist.
