Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8740542, here are decompositions:

11 + 8740531 = 8740542
23 + 8740519 = 8740542
89 + 8740453 = 8740542
113 + 8740429 = 8740542
131 + 8740411 = 8740542
149 + 8740393 = 8740542
211 + 8740331 = 8740542
241 + 8740301 = 8740542

Showing the first eight; more decompositions exist.
