Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8741668, here are decompositions:

29 + 8741639 = 8741668
59 + 8741609 = 8741668
197 + 8741471 = 8741668
347 + 8741321 = 8741668
359 + 8741309 = 8741668
389 + 8741279 = 8741668
521 + 8741147 = 8741668
569 + 8741099 = 8741668

Showing the first eight; more decompositions exist.
