Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31458822, here are decompositions:

23 + 31458799 = 31458822
61 + 31458761 = 31458822
103 + 31458719 = 31458822
113 + 31458709 = 31458822
179 + 31458643 = 31458822
191 + 31458631 = 31458822
229 + 31458593 = 31458822
233 + 31458589 = 31458822

Showing the first eight; more decompositions exist.
