Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8591654, here are decompositions:

31 + 8591623 = 8591654
37 + 8591617 = 8591654
61 + 8591593 = 8591654
67 + 8591587 = 8591654
223 + 8591431 = 8591654
277 + 8591377 = 8591654
397 + 8591257 = 8591654
523 + 8591131 = 8591654

Showing the first eight; more decompositions exist.
