Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537266, here are decompositions:

23 + 31537243 = 31537266
37 + 31537229 = 31537266
43 + 31537223 = 31537266
113 + 31537153 = 31537266
139 + 31537127 = 31537266
179 + 31537087 = 31537266
223 + 31537043 = 31537266
227 + 31537039 = 31537266

Showing the first eight; more decompositions exist.
