Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613942, here are decompositions:

103 + 31613839 = 31613942
109 + 31613833 = 31613942
223 + 31613719 = 31613942
313 + 31613629 = 31613942
541 + 31613401 = 31613942
601 + 31613341 = 31613942
751 + 31613191 = 31613942
823 + 31613119 = 31613942

Showing the first eight; more decompositions exist.
