Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31447676, here are decompositions:

3 + 31447673 = 31447676
19 + 31447657 = 31447676
103 + 31447573 = 31447676
199 + 31447477 = 31447676
283 + 31447393 = 31447676
313 + 31447363 = 31447676
409 + 31447267 = 31447676
487 + 31447189 = 31447676

Showing the first eight; more decompositions exist.
