Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8740286, here are decompositions:

13 + 8740273 = 8740286
67 + 8740219 = 8740286
103 + 8740183 = 8740286
157 + 8740129 = 8740286
199 + 8740087 = 8740286
283 + 8740003 = 8740286
349 + 8739937 = 8740286
367 + 8739919 = 8740286

Showing the first eight; more decompositions exist.
