Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608, here are decompositions:

7 + 31601 = 31608
41 + 31567 = 31608
61 + 31547 = 31608
67 + 31541 = 31608
97 + 31511 = 31608
127 + 31481 = 31608
131 + 31477 = 31608
139 + 31469 = 31608

Showing the first eight; more decompositions exist.
