Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607226, here are decompositions:

19 + 31607207 = 31607226
73 + 31607153 = 31607226
89 + 31607137 = 31607226
139 + 31607087 = 31607226
179 + 31607047 = 31607226
229 + 31606997 = 31607226
263 + 31606963 = 31607226
269 + 31606957 = 31607226

Showing the first eight; more decompositions exist.
