Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613480, here are decompositions:

43 + 31613437 = 31613480
79 + 31613401 = 31613480
97 + 31613383 = 31613480
103 + 31613377 = 31613480
139 + 31613341 = 31613480
337 + 31613143 = 31613480
373 + 31613107 = 31613480
499 + 31612981 = 31613480

Showing the first eight; more decompositions exist.
