Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502226, here are decompositions:

13 + 31502213 = 31502226
37 + 31502189 = 31502226
43 + 31502183 = 31502226
79 + 31502147 = 31502226
97 + 31502129 = 31502226
113 + 31502113 = 31502226
127 + 31502099 = 31502226
269 + 31501957 = 31502226

Showing the first eight; more decompositions exist.
