Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8740566, here are decompositions:

5 + 8740561 = 8740566
7 + 8740559 = 8740566
47 + 8740519 = 8740566
73 + 8740493 = 8740566
113 + 8740453 = 8740566
137 + 8740429 = 8740566
139 + 8740427 = 8740566
173 + 8740393 = 8740566

Showing the first eight; more decompositions exist.
