Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562088, here are decompositions:

31 + 31562057 = 31562088
71 + 31562017 = 31562088
79 + 31562009 = 31562088
149 + 31561939 = 31562088
241 + 31561847 = 31562088
277 + 31561811 = 31562088
281 + 31561807 = 31562088
307 + 31561781 = 31562088

Showing the first eight; more decompositions exist.
