Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8740722, here are decompositions:

41 + 8740681 = 8740722
43 + 8740679 = 8740722
73 + 8740649 = 8740722
79 + 8740643 = 8740722
131 + 8740591 = 8740722
163 + 8740559 = 8740722
181 + 8740541 = 8740722
191 + 8740531 = 8740722

Showing the first eight; more decompositions exist.
