Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562008, here are decompositions:

41 + 31561967 = 31562008
89 + 31561919 = 31562008
197 + 31561811 = 31562008
227 + 31561781 = 31562008
311 + 31561697 = 31562008
347 + 31561661 = 31562008
431 + 31561577 = 31562008
461 + 31561547 = 31562008

Showing the first eight; more decompositions exist.
