Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747162, here are decompositions:

3 + 8747159 = 8747162
43 + 8747119 = 8747162
79 + 8747083 = 8747162
163 + 8746999 = 8747162
199 + 8746963 = 8747162
223 + 8746939 = 8747162
241 + 8746921 = 8747162
283 + 8746879 = 8747162

Showing the first eight; more decompositions exist.
