Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8619198, here are decompositions:

31 + 8619167 = 8619198
41 + 8619157 = 8619198
47 + 8619151 = 8619198
67 + 8619131 = 8619198
97 + 8619101 = 8619198
101 + 8619097 = 8619198
127 + 8619071 = 8619198
131 + 8619067 = 8619198

Showing the first eight; more decompositions exist.
