Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668672, here are decompositions:

29 + 8668643 = 8668672
59 + 8668613 = 8668672
101 + 8668571 = 8668672
149 + 8668523 = 8668672
251 + 8668421 = 8668672
269 + 8668403 = 8668672
293 + 8668379 = 8668672
479 + 8668193 = 8668672

Showing the first eight; more decompositions exist.
