Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8743216, here are decompositions:

3 + 8743213 = 8743216
47 + 8743169 = 8743216
113 + 8743103 = 8743216
137 + 8743079 = 8743216
149 + 8743067 = 8743216
173 + 8743043 = 8743216
179 + 8743037 = 8743216
197 + 8743019 = 8743216

Showing the first eight; more decompositions exist.
