Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31471092, here are decompositions:

13 + 31471079 = 31471092
41 + 31471051 = 31471092
61 + 31471031 = 31471092
101 + 31470991 = 31471092
139 + 31470953 = 31471092
151 + 31470941 = 31471092
179 + 31470913 = 31471092
181 + 31470911 = 31471092

Showing the first eight; more decompositions exist.
