Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448264, here are decompositions:

31 + 31448233 = 31448264
73 + 31448191 = 31448264
103 + 31448161 = 31448264
193 + 31448071 = 31448264
241 + 31448023 = 31448264
277 + 31447987 = 31448264
307 + 31447957 = 31448264
313 + 31447951 = 31448264

Showing the first eight; more decompositions exist.
