Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8740020, here are decompositions:

17 + 8740003 = 8740020
53 + 8739967 = 8740020
59 + 8739961 = 8740020
67 + 8739953 = 8740020
83 + 8739937 = 8740020
101 + 8739919 = 8740020
103 + 8739917 = 8740020
109 + 8739911 = 8740020

Showing the first eight; more decompositions exist.
