Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747222, here are decompositions:

31 + 8747191 = 8747222
103 + 8747119 = 8747222
139 + 8747083 = 8747222
151 + 8747071 = 8747222
181 + 8747041 = 8747222
223 + 8746999 = 8747222
283 + 8746939 = 8747222
349 + 8746873 = 8747222

Showing the first eight; more decompositions exist.
