Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448858, here are decompositions:

19 + 31448839 = 31448858
37 + 31448821 = 31448858
139 + 31448719 = 31448858
151 + 31448707 = 31448858
211 + 31448647 = 31448858
271 + 31448587 = 31448858
277 + 31448581 = 31448858
307 + 31448551 = 31448858

Showing the first eight; more decompositions exist.
