Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492050, here are decompositions:

17 + 31492033 = 31492050
19 + 31492031 = 31492050
61 + 31491989 = 31492050
67 + 31491983 = 31492050
137 + 31491913 = 31492050
157 + 31491893 = 31492050
257 + 31491793 = 31492050
263 + 31491787 = 31492050

Showing the first eight; more decompositions exist.
