Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8740538, here are decompositions:

7 + 8740531 = 8740538
19 + 8740519 = 8740538
109 + 8740429 = 8740538
127 + 8740411 = 8740538
151 + 8740387 = 8740538
211 + 8740327 = 8740538
409 + 8740129 = 8740538
421 + 8740117 = 8740538

Showing the first eight; more decompositions exist.
