Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8741986, here are decompositions:

3 + 8741983 = 8741986
53 + 8741933 = 8741986
173 + 8741813 = 8741986
233 + 8741753 = 8741986
347 + 8741639 = 8741986
593 + 8741393 = 8741986
677 + 8741309 = 8741986
683 + 8741303 = 8741986

Showing the first eight; more decompositions exist.
