Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8740572, here are decompositions:

11 + 8740561 = 8740572
13 + 8740559 = 8740572
31 + 8740541 = 8740572
41 + 8740531 = 8740572
53 + 8740519 = 8740572
79 + 8740493 = 8740572
179 + 8740393 = 8740572
199 + 8740373 = 8740572

Showing the first eight; more decompositions exist.
