Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8739180, here are decompositions:

11 + 8739169 = 8739180
13 + 8739167 = 8739180
17 + 8739163 = 8739180
53 + 8739127 = 8739180
61 + 8739119 = 8739180
67 + 8739113 = 8739180
83 + 8739097 = 8739180
101 + 8739079 = 8739180

Showing the first eight; more decompositions exist.
