Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8740646, here are decompositions:

3 + 8740643 = 8740646
43 + 8740603 = 8740646
67 + 8740579 = 8740646
127 + 8740519 = 8740646
193 + 8740453 = 8740646
199 + 8740447 = 8740646
373 + 8740273 = 8740646
463 + 8740183 = 8740646

Showing the first eight; more decompositions exist.
