Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475226, here are decompositions:

17 + 31475209 = 31475226
37 + 31475189 = 31475226
67 + 31475159 = 31475226
127 + 31475099 = 31475226
137 + 31475089 = 31475226
157 + 31475069 = 31475226
173 + 31475053 = 31475226
197 + 31475029 = 31475226

Showing the first eight; more decompositions exist.
