Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8684626, here are decompositions:

29 + 8684597 = 8684626
53 + 8684573 = 8684626
89 + 8684537 = 8684626
113 + 8684513 = 8684626
347 + 8684279 = 8684626
359 + 8684267 = 8684626
383 + 8684243 = 8684626
449 + 8684177 = 8684626

Showing the first eight; more decompositions exist.
