Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640676, here are decompositions:

89 + 8640587 = 8640676
173 + 8640503 = 8640676
257 + 8640419 = 8640676
269 + 8640407 = 8640676
347 + 8640329 = 8640676
389 + 8640287 = 8640676
479 + 8640197 = 8640676
617 + 8640059 = 8640676

Showing the first eight; more decompositions exist.
