Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537424, here are decompositions:

97 + 31537327 = 31537424
151 + 31537273 = 31537424
157 + 31537267 = 31537424
181 + 31537243 = 31537424
223 + 31537201 = 31537424
271 + 31537153 = 31537424
277 + 31537147 = 31537424
337 + 31537087 = 31537424

Showing the first eight; more decompositions exist.
