Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562964, here are decompositions:

5 + 31562959 = 31562964
47 + 31562917 = 31562964
53 + 31562911 = 31562964
137 + 31562827 = 31562964
163 + 31562801 = 31562964
197 + 31562767 = 31562964
227 + 31562737 = 31562964
281 + 31562683 = 31562964

Showing the first eight; more decompositions exist.
