Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8690824, here are decompositions:

3 + 8690821 = 8690824
11 + 8690813 = 8690824
41 + 8690783 = 8690824
83 + 8690741 = 8690824
257 + 8690567 = 8690824
293 + 8690531 = 8690824
347 + 8690477 = 8690824
491 + 8690333 = 8690824

Showing the first eight; more decompositions exist.
