Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691162, here are decompositions:

5 + 8691157 = 8691162
43 + 8691119 = 8691162
61 + 8691101 = 8691162
71 + 8691091 = 8691162
191 + 8690971 = 8691162
199 + 8690963 = 8691162
211 + 8690951 = 8691162
241 + 8690921 = 8691162

Showing the first eight; more decompositions exist.
