Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747120, here are decompositions:

37 + 8747083 = 8747120
79 + 8747041 = 8747120
157 + 8746963 = 8747120
163 + 8746957 = 8747120
181 + 8746939 = 8747120
199 + 8746921 = 8747120
241 + 8746879 = 8747120
271 + 8746849 = 8747120

Showing the first eight; more decompositions exist.
