Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641098, here are decompositions:

5 + 8641093 = 8641098
19 + 8641079 = 8641098
131 + 8640967 = 8641098
149 + 8640949 = 8641098
211 + 8640887 = 8641098
227 + 8640871 = 8641098
239 + 8640859 = 8641098
281 + 8640817 = 8641098

Showing the first eight; more decompositions exist.
