Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473228, here are decompositions:

11 + 31473217 = 31473228
19 + 31473209 = 31473228
37 + 31473191 = 31473228
41 + 31473187 = 31473228
67 + 31473161 = 31473228
151 + 31473077 = 31473228
167 + 31473061 = 31473228
191 + 31473037 = 31473228

Showing the first eight; more decompositions exist.
