Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562084, here are decompositions:

31 + 31562053 = 31562084
61 + 31562023 = 31562084
67 + 31562017 = 31562084
157 + 31561927 = 31562084
181 + 31561903 = 31562084
277 + 31561807 = 31562084
283 + 31561801 = 31562084
331 + 31561753 = 31562084

Showing the first eight; more decompositions exist.
