Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618154, here are decompositions:

5 + 8618149 = 8618154
7 + 8618147 = 8618154
23 + 8618131 = 8618154
47 + 8618107 = 8618154
67 + 8618087 = 8618154
71 + 8618083 = 8618154
107 + 8618047 = 8618154
113 + 8618041 = 8618154

Showing the first eight; more decompositions exist.
