Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470634, here are decompositions:

5 + 31470629 = 31470634
11 + 31470623 = 31470634
53 + 31470581 = 31470634
71 + 31470563 = 31470634
191 + 31470443 = 31470634
281 + 31470353 = 31470634
311 + 31470323 = 31470634
467 + 31470167 = 31470634

Showing the first eight; more decompositions exist.
