Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601496, here are decompositions:

7 + 31601489 = 31601496
23 + 31601473 = 31601496
79 + 31601417 = 31601496
89 + 31601407 = 31601496
103 + 31601393 = 31601496
137 + 31601359 = 31601496
139 + 31601357 = 31601496
149 + 31601347 = 31601496

Showing the first eight; more decompositions exist.
