Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613342, here are decompositions:

151 + 31613191 = 31613342
199 + 31613143 = 31613342
223 + 31613119 = 31613342
373 + 31612969 = 31613342
613 + 31612729 = 31613342
769 + 31612573 = 31613342
811 + 31612531 = 31613342
829 + 31612513 = 31613342

Showing the first eight; more decompositions exist.
