Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8688190, here are decompositions:

23 + 8688167 = 8688190
29 + 8688161 = 8688190
47 + 8688143 = 8688190
89 + 8688101 = 8688190
107 + 8688083 = 8688190
113 + 8688077 = 8688190
131 + 8688059 = 8688190
179 + 8688011 = 8688190

Showing the first eight; more decompositions exist.
