Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472226, here are decompositions:

17 + 31472209 = 31472226
43 + 31472183 = 31472226
47 + 31472179 = 31472226
59 + 31472167 = 31472226
67 + 31472159 = 31472226
73 + 31472153 = 31472226
83 + 31472143 = 31472226
103 + 31472123 = 31472226

Showing the first eight; more decompositions exist.
