Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599102, here are decompositions:

43 + 31599059 = 31599102
113 + 31598989 = 31599102
149 + 31598953 = 31599102
163 + 31598939 = 31599102
179 + 31598923 = 31599102
191 + 31598911 = 31599102
193 + 31598909 = 31599102
229 + 31598873 = 31599102

Showing the first eight; more decompositions exist.
