Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747246, here are decompositions:

3 + 8747243 = 8747246
127 + 8747119 = 8747246
163 + 8747083 = 8747246
283 + 8746963 = 8747246
307 + 8746939 = 8747246
367 + 8746879 = 8747246
373 + 8746873 = 8747246
397 + 8746849 = 8747246

Showing the first eight; more decompositions exist.
