Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452264, here are decompositions:

23 + 31452241 = 31452264
31 + 31452233 = 31452264
61 + 31452203 = 31452264
83 + 31452181 = 31452264
127 + 31452137 = 31452264
167 + 31452097 = 31452264
223 + 31452041 = 31452264
251 + 31452013 = 31452264

Showing the first eight; more decompositions exist.
