Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537298, here are decompositions:

31 + 31537267 = 31537298
97 + 31537201 = 31537298
151 + 31537147 = 31537298
211 + 31537087 = 31537298
271 + 31537027 = 31537298
307 + 31536991 = 31537298
601 + 31536697 = 31537298
691 + 31536607 = 31537298

Showing the first eight; more decompositions exist.
