Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475352, here are decompositions:

11 + 31475341 = 31475352
31 + 31475321 = 31475352
101 + 31475251 = 31475352
109 + 31475243 = 31475352
163 + 31475189 = 31475352
193 + 31475159 = 31475352
211 + 31475141 = 31475352
241 + 31475111 = 31475352

Showing the first eight; more decompositions exist.
