Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472324, here are decompositions:

31 + 31472293 = 31472324
157 + 31472167 = 31472324
181 + 31472143 = 31472324
193 + 31472131 = 31472324
271 + 31472053 = 31472324
283 + 31472041 = 31472324
313 + 31472011 = 31472324
613 + 31471711 = 31472324

Showing the first eight; more decompositions exist.
