Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31458164, here are decompositions:

103 + 31458061 = 31458164
151 + 31458013 = 31458164
307 + 31457857 = 31458164
421 + 31457743 = 31458164
457 + 31457707 = 31458164
523 + 31457641 = 31458164
607 + 31457557 = 31458164
823 + 31457341 = 31458164

Showing the first eight; more decompositions exist.
