Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613954, here are decompositions:

157 + 31613797 = 31613954
331 + 31613623 = 31613954
373 + 31613581 = 31613954
571 + 31613383 = 31613954
577 + 31613377 = 31613954
613 + 31613341 = 31613954
727 + 31613227 = 31613954
811 + 31613143 = 31613954

Showing the first eight; more decompositions exist.
