Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613508, here are decompositions:

67 + 31613441 = 31613508
71 + 31613437 = 31613508
97 + 31613411 = 31613508
107 + 31613401 = 31613508
109 + 31613399 = 31613508
131 + 31613377 = 31613508
151 + 31613357 = 31613508
167 + 31613341 = 31613508

Showing the first eight; more decompositions exist.
