Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671646, here are decompositions:

7 + 8671639 = 8671646
13 + 8671633 = 8671646
73 + 8671573 = 8671646
97 + 8671549 = 8671646
127 + 8671519 = 8671646
199 + 8671447 = 8671646
283 + 8671363 = 8671646
307 + 8671339 = 8671646

Showing the first eight; more decompositions exist.
