Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448752, here are decompositions:

11 + 31448741 = 31448752
53 + 31448699 = 31448752
59 + 31448693 = 31448752
113 + 31448639 = 31448752
131 + 31448621 = 31448752
149 + 31448603 = 31448752
173 + 31448579 = 31448752
233 + 31448519 = 31448752

Showing the first eight; more decompositions exist.
