Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31471062, here are decompositions:

11 + 31471051 = 31471062
19 + 31471043 = 31471062
31 + 31471031 = 31471062
61 + 31471001 = 31471062
71 + 31470991 = 31471062
109 + 31470953 = 31471062
149 + 31470913 = 31471062
151 + 31470911 = 31471062

Showing the first eight; more decompositions exist.
