Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747166, here are decompositions:

7 + 8747159 = 8747166
47 + 8747119 = 8747166
73 + 8747093 = 8747166
83 + 8747083 = 8747166
167 + 8746999 = 8747166
199 + 8746967 = 8747166
227 + 8746939 = 8747166
229 + 8746937 = 8747166

Showing the first eight; more decompositions exist.
