Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599054, here are decompositions:

101 + 31598953 = 31599054
107 + 31598947 = 31599054
127 + 31598927 = 31599054
131 + 31598923 = 31599054
167 + 31598887 = 31599054
181 + 31598873 = 31599054
191 + 31598863 = 31599054
197 + 31598857 = 31599054

Showing the first eight; more decompositions exist.
