Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8737280, here are decompositions:

3 + 8737277 = 8737280
31 + 8737249 = 8737280
37 + 8737243 = 8737280
43 + 8737237 = 8737280
103 + 8737177 = 8737280
127 + 8737153 = 8737280
151 + 8737129 = 8737280
163 + 8737117 = 8737280

Showing the first eight; more decompositions exist.
