Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448722, here are decompositions:

3 + 31448719 = 31448722
5 + 31448717 = 31448722
23 + 31448699 = 31448722
29 + 31448693 = 31448722
83 + 31448639 = 31448722
101 + 31448621 = 31448722
353 + 31448369 = 31448722
401 + 31448321 = 31448722

Showing the first eight; more decompositions exist.
