Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562048, here are decompositions:

31 + 31562017 = 31562048
79 + 31561969 = 31562048
109 + 31561939 = 31562048
241 + 31561807 = 31562048
337 + 31561711 = 31562048
379 + 31561669 = 31562048
499 + 31561549 = 31562048
619 + 31561429 = 31562048

Showing the first eight; more decompositions exist.
