Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537308, here are decompositions:

37 + 31537271 = 31537308
41 + 31537267 = 31537308
79 + 31537229 = 31537308
107 + 31537201 = 31537308
157 + 31537151 = 31537308
181 + 31537127 = 31537308
211 + 31537097 = 31537308
269 + 31537039 = 31537308

Showing the first eight; more decompositions exist.
