Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747156, here are decompositions:

37 + 8747119 = 8747156
73 + 8747083 = 8747156
157 + 8746999 = 8747156
193 + 8746963 = 8747156
199 + 8746957 = 8747156
277 + 8746879 = 8747156
283 + 8746873 = 8747156
307 + 8746849 = 8747156

Showing the first eight; more decompositions exist.
