Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448016, here are decompositions:

29 + 31447987 = 31448016
53 + 31447963 = 31448016
59 + 31447957 = 31448016
113 + 31447903 = 31448016
163 + 31447853 = 31448016
179 + 31447837 = 31448016
233 + 31447783 = 31448016
349 + 31447667 = 31448016

Showing the first eight; more decompositions exist.
