Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613474, here are decompositions:

37 + 31613437 = 31613474
73 + 31613401 = 31613474
97 + 31613377 = 31613474
283 + 31613191 = 31613474
331 + 31613143 = 31613474
337 + 31613137 = 31613474
367 + 31613107 = 31613474
421 + 31613053 = 31613474

Showing the first eight; more decompositions exist.
