Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562994, here are decompositions:

7 + 31562987 = 31562994
11 + 31562983 = 31562994
13 + 31562981 = 31562994
83 + 31562911 = 31562994
167 + 31562827 = 31562994
193 + 31562801 = 31562994
227 + 31562767 = 31562994
257 + 31562737 = 31562994

Showing the first eight; more decompositions exist.
