Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8736646, here are decompositions:

29 + 8736617 = 8736646
53 + 8736593 = 8736646
137 + 8736509 = 8736646
173 + 8736473 = 8736646
197 + 8736449 = 8736646
383 + 8736263 = 8736646
467 + 8736179 = 8736646
557 + 8736089 = 8736646

Showing the first eight; more decompositions exist.
