Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601424, here are decompositions:

7 + 31601417 = 31601424
13 + 31601411 = 31601424
17 + 31601407 = 31601424
31 + 31601393 = 31601424
67 + 31601357 = 31601424
83 + 31601341 = 31601424
157 + 31601267 = 31601424
233 + 31601191 = 31601424

Showing the first eight; more decompositions exist.
