Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590344, here are decompositions:

31 + 31590313 = 31590344
67 + 31590277 = 31590344
103 + 31590241 = 31590344
157 + 31590187 = 31590344
211 + 31590133 = 31590344
223 + 31590121 = 31590344
283 + 31590061 = 31590344
307 + 31590037 = 31590344

Showing the first eight; more decompositions exist.
