Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747078, here are decompositions:

7 + 8747071 = 8747078
37 + 8747041 = 8747078
79 + 8746999 = 8747078
139 + 8746939 = 8747078
157 + 8746921 = 8747078
199 + 8746879 = 8747078
229 + 8746849 = 8747078
271 + 8746807 = 8747078

Showing the first eight; more decompositions exist.
