Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537246, here are decompositions:

3 + 31537243 = 31537246
17 + 31537229 = 31537246
23 + 31537223 = 31537246
113 + 31537133 = 31537246
149 + 31537097 = 31537246
197 + 31537049 = 31537246
263 + 31536983 = 31537246
383 + 31536863 = 31537246

Showing the first eight; more decompositions exist.
