Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537274, here are decompositions:

3 + 31537271 = 31537274
7 + 31537267 = 31537274
31 + 31537243 = 31537274
73 + 31537201 = 31537274
127 + 31537147 = 31537274
271 + 31537003 = 31537274
283 + 31536991 = 31537274
331 + 31536943 = 31537274

Showing the first eight; more decompositions exist.
