Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492134, here are decompositions:

41 + 31492093 = 31492134
43 + 31492091 = 31492134
53 + 31492081 = 31492134
61 + 31492073 = 31492134
67 + 31492067 = 31492134
73 + 31492061 = 31492134
83 + 31492051 = 31492134
101 + 31492033 = 31492134

Showing the first eight; more decompositions exist.
