Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492122, here are decompositions:

29 + 31492093 = 31492122
31 + 31492091 = 31492122
41 + 31492081 = 31492122
43 + 31492079 = 31492122
61 + 31492061 = 31492122
71 + 31492051 = 31492122
89 + 31492033 = 31492122
139 + 31491983 = 31492122

Showing the first eight; more decompositions exist.
