Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672884, here are decompositions:

23 + 8672861 = 8672884
53 + 8672831 = 8672884
83 + 8672801 = 8672884
197 + 8672687 = 8672884
263 + 8672621 = 8672884
383 + 8672501 = 8672884
401 + 8672483 = 8672884
443 + 8672441 = 8672884

Showing the first eight; more decompositions exist.
