Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691150, here are decompositions:

23 + 8691127 = 8691150
31 + 8691119 = 8691150
59 + 8691091 = 8691150
107 + 8691043 = 8691150
131 + 8691019 = 8691150
179 + 8690971 = 8691150
191 + 8690959 = 8691150
197 + 8690953 = 8691150

Showing the first eight; more decompositions exist.
