Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448664, here are decompositions:

17 + 31448647 = 31448664
43 + 31448621 = 31448664
61 + 31448603 = 31448664
83 + 31448581 = 31448664
113 + 31448551 = 31448664
131 + 31448533 = 31448664
157 + 31448507 = 31448664
241 + 31448423 = 31448664

Showing the first eight; more decompositions exist.
