Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492358, here are decompositions:

97 + 31492261 = 31492358
277 + 31492081 = 31492358
307 + 31492051 = 31492358
571 + 31491787 = 31492358
631 + 31491727 = 31492358
661 + 31491697 = 31492358
739 + 31491619 = 31492358
769 + 31491589 = 31492358

Showing the first eight; more decompositions exist.
