Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562632, here are decompositions:

5 + 31562627 = 31562632
11 + 31562621 = 31562632
29 + 31562603 = 31562632
89 + 31562543 = 31562632
113 + 31562519 = 31562632
131 + 31562501 = 31562632
149 + 31562483 = 31562632
191 + 31562441 = 31562632

Showing the first eight; more decompositions exist.
