Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448536, here are decompositions:

3 + 31448533 = 31448536
17 + 31448519 = 31448536
29 + 31448507 = 31448536
89 + 31448447 = 31448536
113 + 31448423 = 31448536
167 + 31448369 = 31448536
227 + 31448309 = 31448536
233 + 31448303 = 31448536

Showing the first eight; more decompositions exist.
