Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562958, here are decompositions:

41 + 31562917 = 31562958
47 + 31562911 = 31562958
109 + 31562849 = 31562958
131 + 31562827 = 31562958
157 + 31562801 = 31562958
179 + 31562779 = 31562958
181 + 31562777 = 31562958
191 + 31562767 = 31562958

Showing the first eight; more decompositions exist.
