Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31471084, here are decompositions:

5 + 31471079 = 31471084
41 + 31471043 = 31471084
53 + 31471031 = 31471084
83 + 31471001 = 31471084
107 + 31470977 = 31471084
131 + 31470953 = 31471084
167 + 31470917 = 31471084
173 + 31470911 = 31471084

Showing the first eight; more decompositions exist.
