Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523294, here are decompositions:

43 + 31523251 = 31523294
67 + 31523227 = 31523294
73 + 31523221 = 31523294
151 + 31523143 = 31523294
163 + 31523131 = 31523294
181 + 31523113 = 31523294
241 + 31523053 = 31523294
307 + 31522987 = 31523294

Showing the first eight; more decompositions exist.
