Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492162, here are decompositions:

5 + 31492157 = 31492162
71 + 31492091 = 31492162
83 + 31492079 = 31492162
89 + 31492073 = 31492162
101 + 31492061 = 31492162
131 + 31492031 = 31492162
173 + 31491989 = 31492162
179 + 31491983 = 31492162

Showing the first eight; more decompositions exist.
