Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492110, here are decompositions:

17 + 31492093 = 31492110
19 + 31492091 = 31492110
29 + 31492081 = 31492110
31 + 31492079 = 31492110
37 + 31492073 = 31492110
43 + 31492067 = 31492110
59 + 31492051 = 31492110
79 + 31492031 = 31492110

Showing the first eight; more decompositions exist.
