Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492104, here are decompositions:

11 + 31492093 = 31492104
13 + 31492091 = 31492104
23 + 31492081 = 31492104
31 + 31492073 = 31492104
37 + 31492067 = 31492104
43 + 31492061 = 31492104
53 + 31492051 = 31492104
71 + 31492033 = 31492104

Showing the first eight; more decompositions exist.
