Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542306, here are decompositions:

73 + 31542233 = 31542306
109 + 31542197 = 31542306
157 + 31542149 = 31542306
193 + 31542113 = 31542306
223 + 31542083 = 31542306
239 + 31542067 = 31542306
269 + 31542037 = 31542306
283 + 31542023 = 31542306

Showing the first eight; more decompositions exist.
