Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8732286, here are decompositions:

29 + 8732257 = 8732286
47 + 8732239 = 8732286
89 + 8732197 = 8732286
97 + 8732189 = 8732286
127 + 8732159 = 8732286
149 + 8732137 = 8732286
163 + 8732123 = 8732286
193 + 8732093 = 8732286

Showing the first eight; more decompositions exist.
