Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31471710, here are decompositions:

7 + 31471703 = 31471710
13 + 31471697 = 31471710
29 + 31471681 = 31471710
43 + 31471667 = 31471710
47 + 31471663 = 31471710
71 + 31471639 = 31471710
73 + 31471637 = 31471710
89 + 31471621 = 31471710

Showing the first eight; more decompositions exist.
