Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8716646, here are decompositions:

7 + 8716639 = 8716646
19 + 8716627 = 8716646
67 + 8716579 = 8716646
79 + 8716567 = 8716646
157 + 8716489 = 8716646
193 + 8716453 = 8716646
199 + 8716447 = 8716646
397 + 8716249 = 8716646

Showing the first eight; more decompositions exist.
