Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448162, here are decompositions:

13 + 31448149 = 31448162
139 + 31448023 = 31448162
199 + 31447963 = 31448162
211 + 31447951 = 31448162
349 + 31447813 = 31448162
379 + 31447783 = 31448162
769 + 31447393 = 31448162
829 + 31447333 = 31448162

Showing the first eight; more decompositions exist.
