Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747100, here are decompositions:

7 + 8747093 = 8747100
17 + 8747083 = 8747100
29 + 8747071 = 8747100
59 + 8747041 = 8747100
101 + 8746999 = 8747100
137 + 8746963 = 8747100
151 + 8746949 = 8747100
163 + 8746937 = 8747100

Showing the first eight; more decompositions exist.
