Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8739930, here are decompositions:

11 + 8739919 = 8739930
13 + 8739917 = 8739930
19 + 8739911 = 8739930
29 + 8739901 = 8739930
47 + 8739883 = 8739930
53 + 8739877 = 8739930
61 + 8739869 = 8739930
79 + 8739851 = 8739930

Showing the first eight; more decompositions exist.
