Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448652, here are decompositions:

5 + 31448647 = 31448652
13 + 31448639 = 31448652
31 + 31448621 = 31448652
71 + 31448581 = 31448652
73 + 31448579 = 31448652
101 + 31448551 = 31448652
173 + 31448479 = 31448652
229 + 31448423 = 31448652

Showing the first eight; more decompositions exist.
