Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8739120, here are decompositions:

7 + 8739113 = 8739120
23 + 8739097 = 8739120
41 + 8739079 = 8739120
67 + 8739053 = 8739120
97 + 8739023 = 8739120
113 + 8739007 = 8739120
157 + 8738963 = 8739120
163 + 8738957 = 8739120

Showing the first eight; more decompositions exist.
