Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8741286, here are decompositions:

7 + 8741279 = 8741286
17 + 8741269 = 8741286
53 + 8741233 = 8741286
83 + 8741203 = 8741286
137 + 8741149 = 8741286
139 + 8741147 = 8741286
149 + 8741137 = 8741286
157 + 8741129 = 8741286

Showing the first eight; more decompositions exist.
