Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8658492, here are decompositions:

23 + 8658469 = 8658492
61 + 8658431 = 8658492
79 + 8658413 = 8658492
109 + 8658383 = 8658492
163 + 8658329 = 8658492
179 + 8658313 = 8658492
331 + 8658161 = 8658492
383 + 8658109 = 8658492

Showing the first eight; more decompositions exist.
