Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8740394, here are decompositions:

7 + 8740387 = 8740394
67 + 8740327 = 8740394
73 + 8740321 = 8740394
211 + 8740183 = 8740394
277 + 8740117 = 8740394
283 + 8740111 = 8740394
307 + 8740087 = 8740394
433 + 8739961 = 8740394

Showing the first eight; more decompositions exist.
