Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492092, here are decompositions:

11 + 31492081 = 31492092
13 + 31492079 = 31492092
19 + 31492073 = 31492092
31 + 31492061 = 31492092
41 + 31492051 = 31492092
59 + 31492033 = 31492092
61 + 31492031 = 31492092
103 + 31491989 = 31492092

Showing the first eight; more decompositions exist.
