Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537484, here are decompositions:

3 + 31537481 = 31537484
7 + 31537477 = 31537484
157 + 31537327 = 31537484
211 + 31537273 = 31537484
241 + 31537243 = 31537484
283 + 31537201 = 31537484
331 + 31537153 = 31537484
337 + 31537147 = 31537484

Showing the first eight; more decompositions exist.
