Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448634, here are decompositions:

13 + 31448621 = 31448634
31 + 31448603 = 31448634
47 + 31448587 = 31448634
53 + 31448581 = 31448634
83 + 31448551 = 31448634
101 + 31448533 = 31448634
127 + 31448507 = 31448634
211 + 31448423 = 31448634

Showing the first eight; more decompositions exist.
