Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8740730, here are decompositions:

3 + 8740727 = 8740730
73 + 8740657 = 8740730
127 + 8740603 = 8740730
139 + 8740591 = 8740730
151 + 8740579 = 8740730
199 + 8740531 = 8740730
211 + 8740519 = 8740730
277 + 8740453 = 8740730

Showing the first eight; more decompositions exist.
