Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537226, here are decompositions:

3 + 31537223 = 31537226
73 + 31537153 = 31537226
79 + 31537147 = 31537226
139 + 31537087 = 31537226
199 + 31537027 = 31537226
223 + 31537003 = 31537226
283 + 31536943 = 31537226
379 + 31536847 = 31537226

Showing the first eight; more decompositions exist.
