Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492956, here are decompositions:

13 + 31492943 = 31492956
23 + 31492933 = 31492956
97 + 31492859 = 31492956
107 + 31492849 = 31492956
109 + 31492847 = 31492956
179 + 31492777 = 31492956
199 + 31492757 = 31492956
293 + 31492663 = 31492956

Showing the first eight; more decompositions exist.
