Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492152, here are decompositions:

59 + 31492093 = 31492152
61 + 31492091 = 31492152
71 + 31492081 = 31492152
73 + 31492079 = 31492152
79 + 31492073 = 31492152
101 + 31492051 = 31492152
163 + 31491989 = 31492152
193 + 31491959 = 31492152

Showing the first eight; more decompositions exist.
