Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8740280, here are decompositions:

7 + 8740273 = 8740280
61 + 8740219 = 8740280
97 + 8740183 = 8740280
151 + 8740129 = 8740280
163 + 8740117 = 8740280
193 + 8740087 = 8740280
277 + 8740003 = 8740280
313 + 8739967 = 8740280

Showing the first eight; more decompositions exist.
