Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590562, here are decompositions:

5 + 31590557 = 31590562
11 + 31590551 = 31590562
83 + 31590479 = 31590562
149 + 31590413 = 31590562
191 + 31590371 = 31590562
293 + 31590269 = 31590562
401 + 31590161 = 31590562
491 + 31590071 = 31590562

Showing the first eight; more decompositions exist.
