Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540822, here are decompositions:

113 + 31540709 = 31540822
179 + 31540643 = 31540822
191 + 31540631 = 31540822
293 + 31540529 = 31540822
479 + 31540343 = 31540822
641 + 31540181 = 31540822
659 + 31540163 = 31540822
809 + 31540013 = 31540822

Showing the first eight; more decompositions exist.
