Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747220, here are decompositions:

7 + 8747213 = 8747220
29 + 8747191 = 8747220
61 + 8747159 = 8747220
101 + 8747119 = 8747220
109 + 8747111 = 8747220
127 + 8747093 = 8747220
137 + 8747083 = 8747220
149 + 8747071 = 8747220

Showing the first eight; more decompositions exist.
