Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492102, here are decompositions:

11 + 31492091 = 31492102
23 + 31492079 = 31492102
29 + 31492073 = 31492102
41 + 31492061 = 31492102
71 + 31492031 = 31492102
113 + 31491989 = 31492102
311 + 31491791 = 31492102
353 + 31491749 = 31492102

Showing the first eight; more decompositions exist.
