Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8739990, here are decompositions:

23 + 8739967 = 8739990
29 + 8739961 = 8739990
37 + 8739953 = 8739990
53 + 8739937 = 8739990
71 + 8739919 = 8739990
73 + 8739917 = 8739990
79 + 8739911 = 8739990
89 + 8739901 = 8739990

Showing the first eight; more decompositions exist.
