Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8739980, here are decompositions:

13 + 8739967 = 8739980
19 + 8739961 = 8739980
43 + 8739937 = 8739980
61 + 8739919 = 8739980
79 + 8739901 = 8739980
97 + 8739883 = 8739980
103 + 8739877 = 8739980
157 + 8739823 = 8739980

Showing the first eight; more decompositions exist.
