Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601448, here are decompositions:

31 + 31601417 = 31601448
37 + 31601411 = 31601448
41 + 31601407 = 31601448
89 + 31601359 = 31601448
101 + 31601347 = 31601448
107 + 31601341 = 31601448
181 + 31601267 = 31601448
257 + 31601191 = 31601448

Showing the first eight; more decompositions exist.
