Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618196, here are decompositions:

23 + 8618173 = 8618196
47 + 8618149 = 8618196
89 + 8618107 = 8618196
107 + 8618089 = 8618196
109 + 8618087 = 8618196
113 + 8618083 = 8618196
137 + 8618059 = 8618196
149 + 8618047 = 8618196

Showing the first eight; more decompositions exist.
