Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738120, here are decompositions:

19 + 8738101 = 8738120
31 + 8738089 = 8738120
37 + 8738083 = 8738120
67 + 8738053 = 8738120
73 + 8738047 = 8738120
109 + 8738011 = 8738120
199 + 8737921 = 8738120
271 + 8737849 = 8738120

Showing the first eight; more decompositions exist.
