Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448994, here are decompositions:

7 + 31448987 = 31448994
97 + 31448897 = 31448994
103 + 31448891 = 31448994
131 + 31448863 = 31448994
173 + 31448821 = 31448994
191 + 31448803 = 31448994
277 + 31448717 = 31448994
281 + 31448713 = 31448994

Showing the first eight; more decompositions exist.
