Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31447264, here are decompositions:

11 + 31447253 = 31447264
47 + 31447217 = 31447264
53 + 31447211 = 31447264
83 + 31447181 = 31447264
131 + 31447133 = 31447264
263 + 31447001 = 31447264
281 + 31446983 = 31447264
311 + 31446953 = 31447264

Showing the first eight; more decompositions exist.
