Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537386, here are decompositions:

47 + 31537339 = 31537386
59 + 31537327 = 31537386
73 + 31537313 = 31537386
79 + 31537307 = 31537386
113 + 31537273 = 31537386
157 + 31537229 = 31537386
163 + 31537223 = 31537386
233 + 31537153 = 31537386

Showing the first eight; more decompositions exist.
