Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599050, here are decompositions:

61 + 31598989 = 31599050
97 + 31598953 = 31599050
103 + 31598947 = 31599050
127 + 31598923 = 31599050
139 + 31598911 = 31599050
163 + 31598887 = 31599050
193 + 31598857 = 31599050
211 + 31598839 = 31599050

Showing the first eight; more decompositions exist.
