Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8743942, here are decompositions:

5 + 8743937 = 8743942
23 + 8743919 = 8743942
29 + 8743913 = 8743942
41 + 8743901 = 8743942
59 + 8743883 = 8743942
89 + 8743853 = 8743942
173 + 8743769 = 8743942
269 + 8743673 = 8743942

Showing the first eight; more decompositions exist.
