Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452294, here are decompositions:

11 + 31452283 = 31452294
53 + 31452241 = 31452294
61 + 31452233 = 31452294
113 + 31452181 = 31452294
157 + 31452137 = 31452294
163 + 31452131 = 31452294
173 + 31452121 = 31452294
197 + 31452097 = 31452294

Showing the first eight; more decompositions exist.
