Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621098, here are decompositions:

11 + 8621087 = 8621098
47 + 8621051 = 8621098
89 + 8621009 = 8621098
149 + 8620949 = 8621098
251 + 8620847 = 8621098
257 + 8620841 = 8621098
359 + 8620739 = 8621098
461 + 8620637 = 8621098

Showing the first eight; more decompositions exist.
