Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31471676, here are decompositions:

13 + 31471663 = 31471676
37 + 31471639 = 31471676
43 + 31471633 = 31471676
97 + 31471579 = 31471676
127 + 31471549 = 31471676
463 + 31471213 = 31471676
787 + 31470889 = 31471676
823 + 31470853 = 31471676

Showing the first eight; more decompositions exist.
