Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532226, here are decompositions:

7 + 31532219 = 31532226
17 + 31532209 = 31532226
23 + 31532203 = 31532226
59 + 31532167 = 31532226
109 + 31532117 = 31532226
113 + 31532113 = 31532226
137 + 31532089 = 31532226
163 + 31532063 = 31532226

Showing the first eight; more decompositions exist.
