Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8739958, here are decompositions:

5 + 8739953 = 8739958
41 + 8739917 = 8739958
47 + 8739911 = 8739958
89 + 8739869 = 8739958
107 + 8739851 = 8739958
131 + 8739827 = 8739958
137 + 8739821 = 8739958
191 + 8739767 = 8739958

Showing the first eight; more decompositions exist.
