Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448832, here are decompositions:

11 + 31448821 = 31448832
29 + 31448803 = 31448832
113 + 31448719 = 31448832
139 + 31448693 = 31448832
193 + 31448639 = 31448832
211 + 31448621 = 31448832
229 + 31448603 = 31448832
251 + 31448581 = 31448832

Showing the first eight; more decompositions exist.
