Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31471708, here are decompositions:

5 + 31471703 = 31471708
11 + 31471697 = 31471708
41 + 31471667 = 31471708
71 + 31471637 = 31471708
131 + 31471577 = 31471708
197 + 31471511 = 31471708
227 + 31471481 = 31471708
239 + 31471469 = 31471708

Showing the first eight; more decompositions exist.
