Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448052, here are decompositions:

19 + 31448033 = 31448052
29 + 31448023 = 31448052
89 + 31447963 = 31448052
101 + 31447951 = 31448052
149 + 31447903 = 31448052
151 + 31447901 = 31448052
199 + 31447853 = 31448052
239 + 31447813 = 31448052

Showing the first eight; more decompositions exist.
