Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448824, here are decompositions:

3 + 31448821 = 31448824
83 + 31448741 = 31448824
107 + 31448717 = 31448824
131 + 31448693 = 31448824
317 + 31448507 = 31448824
401 + 31448423 = 31448824
443 + 31448381 = 31448824
503 + 31448321 = 31448824

Showing the first eight; more decompositions exist.
