Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562168, here are decompositions:

31 + 31562137 = 31562168
61 + 31562107 = 31562168
151 + 31562017 = 31562168
199 + 31561969 = 31562168
229 + 31561939 = 31562168
241 + 31561927 = 31562168
367 + 31561801 = 31562168
439 + 31561729 = 31562168

Showing the first eight; more decompositions exist.
