Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8684578, here are decompositions:

5 + 8684573 = 8684578
41 + 8684537 = 8684578
107 + 8684471 = 8684578
167 + 8684411 = 8684578
311 + 8684267 = 8684578
317 + 8684261 = 8684578
347 + 8684231 = 8684578
389 + 8684189 = 8684578

Showing the first eight; more decompositions exist.
