Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31531414, here are decompositions:

11 + 31531403 = 31531414
113 + 31531301 = 31531414
197 + 31531217 = 31531414
251 + 31531163 = 31531414
521 + 31530893 = 31531414
587 + 31530827 = 31531414
617 + 31530797 = 31531414
641 + 31530773 = 31531414

Showing the first eight; more decompositions exist.
