Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31513594, here are decompositions:

191 + 31513403 = 31513594
263 + 31513331 = 31513594
401 + 31513193 = 31513594
503 + 31513091 = 31513594
521 + 31513073 = 31513594
557 + 31513037 = 31513594
587 + 31513007 = 31513594
647 + 31512947 = 31513594

Showing the first eight; more decompositions exist.
