Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448682, here are decompositions:

43 + 31448639 = 31448682
61 + 31448621 = 31448682
79 + 31448603 = 31448682
101 + 31448581 = 31448682
103 + 31448579 = 31448682
131 + 31448551 = 31448682
149 + 31448533 = 31448682
163 + 31448519 = 31448682

Showing the first eight; more decompositions exist.
