Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8690190, here are decompositions:

13 + 8690177 = 8690190
17 + 8690173 = 8690190
71 + 8690119 = 8690190
73 + 8690117 = 8690190
97 + 8690093 = 8690190
101 + 8690089 = 8690190
127 + 8690063 = 8690190
149 + 8690041 = 8690190

Showing the first eight; more decompositions exist.
