Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537304, here are decompositions:

31 + 31537273 = 31537304
37 + 31537267 = 31537304
61 + 31537243 = 31537304
103 + 31537201 = 31537304
151 + 31537153 = 31537304
157 + 31537147 = 31537304
277 + 31537027 = 31537304
313 + 31536991 = 31537304

Showing the first eight; more decompositions exist.
