Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8740738, here are decompositions:

11 + 8740727 = 8740738
59 + 8740679 = 8740738
89 + 8740649 = 8740738
131 + 8740607 = 8740738
179 + 8740559 = 8740738
197 + 8740541 = 8740738
311 + 8740427 = 8740738
401 + 8740337 = 8740738

Showing the first eight; more decompositions exist.
