Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31471098, here are decompositions:

5 + 31471093 = 31471098
7 + 31471091 = 31471098
19 + 31471079 = 31471098
47 + 31471051 = 31471098
67 + 31471031 = 31471098
97 + 31471001 = 31471098
101 + 31470997 = 31471098
107 + 31470991 = 31471098

Showing the first eight; more decompositions exist.
