Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492194, here are decompositions:

31 + 31492163 = 31492194
37 + 31492157 = 31492194
101 + 31492093 = 31492194
103 + 31492091 = 31492194
113 + 31492081 = 31492194
127 + 31492067 = 31492194
163 + 31492031 = 31492194
211 + 31491983 = 31492194

Showing the first eight; more decompositions exist.
