Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590350, here are decompositions:

7 + 31590343 = 31590350
37 + 31590313 = 31590350
73 + 31590277 = 31590350
109 + 31590241 = 31590350
139 + 31590211 = 31590350
163 + 31590187 = 31590350
229 + 31590121 = 31590350
313 + 31590037 = 31590350

Showing the first eight; more decompositions exist.
