Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562080, here are decompositions:

23 + 31562057 = 31562080
47 + 31562033 = 31562080
71 + 31562009 = 31562080
107 + 31561973 = 31562080
113 + 31561967 = 31562080
233 + 31561847 = 31562080
257 + 31561823 = 31562080
269 + 31561811 = 31562080

Showing the first eight; more decompositions exist.
