Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31458358, here are decompositions:

47 + 31458311 = 31458358
59 + 31458299 = 31458358
167 + 31458191 = 31458358
227 + 31458131 = 31458358
359 + 31457999 = 31458358
389 + 31457969 = 31458358
509 + 31457849 = 31458358
587 + 31457771 = 31458358

Showing the first eight; more decompositions exist.
