Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747180, here are decompositions:

61 + 8747119 = 8747180
97 + 8747083 = 8747180
109 + 8747071 = 8747180
139 + 8747041 = 8747180
181 + 8746999 = 8747180
223 + 8746957 = 8747180
241 + 8746939 = 8747180
307 + 8746873 = 8747180

Showing the first eight; more decompositions exist.
