Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562006, here are decompositions:

13 + 31561993 = 31562006
37 + 31561969 = 31562006
67 + 31561939 = 31562006
79 + 31561927 = 31562006
103 + 31561903 = 31562006
199 + 31561807 = 31562006
277 + 31561729 = 31562006
283 + 31561723 = 31562006

Showing the first eight; more decompositions exist.
