Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537356, here are decompositions:

17 + 31537339 = 31537356
29 + 31537327 = 31537356
43 + 31537313 = 31537356
47 + 31537309 = 31537356
83 + 31537273 = 31537356
89 + 31537267 = 31537356
113 + 31537243 = 31537356
127 + 31537229 = 31537356

Showing the first eight; more decompositions exist.
