Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31458464, here are decompositions:

13 + 31458451 = 31458464
61 + 31458403 = 31458464
277 + 31458187 = 31458464
607 + 31457857 = 31458464
643 + 31457821 = 31458464
727 + 31457737 = 31458464
757 + 31457707 = 31458464
823 + 31457641 = 31458464

Showing the first eight; more decompositions exist.
