Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8680428, here are decompositions:

11 + 8680417 = 8680428
19 + 8680409 = 8680428
37 + 8680391 = 8680428
59 + 8680369 = 8680428
101 + 8680327 = 8680428
131 + 8680297 = 8680428
151 + 8680277 = 8680428
179 + 8680249 = 8680428

Showing the first eight; more decompositions exist.
