Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618120, here are decompositions:

13 + 8618107 = 8618120
31 + 8618089 = 8618120
37 + 8618083 = 8618120
61 + 8618059 = 8618120
73 + 8618047 = 8618120
79 + 8618041 = 8618120
127 + 8617993 = 8618120
193 + 8617927 = 8618120

Showing the first eight; more decompositions exist.
