Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8701272, here are decompositions:

5 + 8701267 = 8701272
29 + 8701243 = 8701272
61 + 8701211 = 8701272
79 + 8701193 = 8701272
109 + 8701163 = 8701272
131 + 8701141 = 8701272
149 + 8701123 = 8701272
191 + 8701081 = 8701272

Showing the first eight; more decompositions exist.
