Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8690108, here are decompositions:

19 + 8690089 = 8690108
67 + 8690041 = 8690108
127 + 8689981 = 8690108
139 + 8689969 = 8690108
151 + 8689957 = 8690108
331 + 8689777 = 8690108
379 + 8689729 = 8690108
397 + 8689711 = 8690108

Showing the first eight; more decompositions exist.
