Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595274, here are decompositions:

23 + 31595251 = 31595274
31 + 31595243 = 31595274
37 + 31595237 = 31595274
97 + 31595177 = 31595274
101 + 31595173 = 31595274
173 + 31595101 = 31595274
211 + 31595063 = 31595274
283 + 31594991 = 31595274

Showing the first eight; more decompositions exist.
