Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590374, here are decompositions:

3 + 31590371 = 31590374
31 + 31590343 = 31590374
61 + 31590313 = 31590374
97 + 31590277 = 31590374
163 + 31590211 = 31590374
241 + 31590133 = 31590374
313 + 31590061 = 31590374
337 + 31590037 = 31590374

Showing the first eight; more decompositions exist.
