Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528950, here are decompositions:

41 + 31528909 = 31528950
97 + 31528853 = 31528950
107 + 31528843 = 31528950
109 + 31528841 = 31528950
127 + 31528823 = 31528950
137 + 31528813 = 31528950
139 + 31528811 = 31528950
149 + 31528801 = 31528950

Showing the first eight; more decompositions exist.
