Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31577226, here are decompositions:

17 + 31577209 = 31577226
29 + 31577197 = 31577226
53 + 31577173 = 31577226
67 + 31577159 = 31577226
97 + 31577129 = 31577226
113 + 31577113 = 31577226
173 + 31577053 = 31577226
269 + 31576957 = 31577226

Showing the first eight; more decompositions exist.
