Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473232, here are decompositions:

23 + 31473209 = 31473232
29 + 31473203 = 31473232
41 + 31473191 = 31473232
59 + 31473173 = 31473232
71 + 31473161 = 31473232
149 + 31473083 = 31473232
191 + 31473041 = 31473232
269 + 31472963 = 31473232

Showing the first eight; more decompositions exist.
