Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448852, here are decompositions:

13 + 31448839 = 31448852
31 + 31448821 = 31448852
139 + 31448713 = 31448852
271 + 31448581 = 31448852
373 + 31448479 = 31448852
439 + 31448413 = 31448852
571 + 31448281 = 31448852
619 + 31448233 = 31448852

Showing the first eight; more decompositions exist.
