Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8740340, here are decompositions:

3 + 8740337 = 8740340
13 + 8740327 = 8740340
19 + 8740321 = 8740340
67 + 8740273 = 8740340
157 + 8740183 = 8740340
211 + 8740129 = 8740340
223 + 8740117 = 8740340
229 + 8740111 = 8740340

Showing the first eight; more decompositions exist.
