Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540834, here are decompositions:

11 + 31540823 = 31540834
47 + 31540787 = 31540834
107 + 31540727 = 31540834
191 + 31540643 = 31540834
197 + 31540637 = 31540834
491 + 31540343 = 31540834
593 + 31540241 = 31540834
617 + 31540217 = 31540834

Showing the first eight; more decompositions exist.
