Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8743930, here are decompositions:

11 + 8743919 = 8743930
17 + 8743913 = 8743930
29 + 8743901 = 8743930
47 + 8743883 = 8743930
113 + 8743817 = 8743930
197 + 8743733 = 8743930
257 + 8743673 = 8743930
347 + 8743583 = 8743930

Showing the first eight; more decompositions exist.
