Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31447662, here are decompositions:

5 + 31447657 = 31447662
19 + 31447643 = 31447662
31 + 31447631 = 31447662
79 + 31447583 = 31447662
89 + 31447573 = 31447662
223 + 31447439 = 31447662
269 + 31447393 = 31447662
283 + 31447379 = 31447662

Showing the first eight; more decompositions exist.
