Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31447362, here are decompositions:

5 + 31447357 = 31447362
29 + 31447333 = 31447362
61 + 31447301 = 31447362
109 + 31447253 = 31447362
151 + 31447211 = 31447362
173 + 31447189 = 31447362
181 + 31447181 = 31447362
229 + 31447133 = 31447362

Showing the first eight; more decompositions exist.
