Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470632, here are decompositions:

3 + 31470629 = 31470632
13 + 31470619 = 31470632
163 + 31470469 = 31470632
223 + 31470409 = 31470632
373 + 31470259 = 31470632
409 + 31470223 = 31470632
433 + 31470199 = 31470632
439 + 31470193 = 31470632

Showing the first eight; more decompositions exist.
