Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613312, here are decompositions:

193 + 31613119 = 31613312
331 + 31612981 = 31613312
373 + 31612939 = 31613312
421 + 31612891 = 31613312
439 + 31612873 = 31613312
691 + 31612621 = 31613312
739 + 31612573 = 31613312
859 + 31612453 = 31613312

Showing the first eight; more decompositions exist.
