Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472264, here are decompositions:

3 + 31472261 = 31472264
73 + 31472191 = 31472264
97 + 31472167 = 31472264
157 + 31472107 = 31472264
211 + 31472053 = 31472264
223 + 31472041 = 31472264
331 + 31471933 = 31472264
433 + 31471831 = 31472264

Showing the first eight; more decompositions exist.
