Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537176, here are decompositions:

23 + 31537153 = 31537176
29 + 31537147 = 31537176
43 + 31537133 = 31537176
79 + 31537097 = 31537176
89 + 31537087 = 31537176
127 + 31537049 = 31537176
137 + 31537039 = 31537176
149 + 31537027 = 31537176

Showing the first eight; more decompositions exist.
