Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31447314, here are decompositions:

13 + 31447301 = 31447314
47 + 31447267 = 31447314
61 + 31447253 = 31447314
97 + 31447217 = 31447314
103 + 31447211 = 31447314
181 + 31447133 = 31447314
211 + 31447103 = 31447314
233 + 31447081 = 31447314

Showing the first eight; more decompositions exist.
