Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31447332, here are decompositions:

31 + 31447301 = 31447332
79 + 31447253 = 31447332
151 + 31447181 = 31447332
199 + 31447133 = 31447332
229 + 31447103 = 31447332
233 + 31447099 = 31447332
251 + 31447081 = 31447332
263 + 31447069 = 31447332

Showing the first eight; more decompositions exist.
