Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8740578, here are decompositions:

17 + 8740561 = 8740578
19 + 8740559 = 8740578
37 + 8740541 = 8740578
47 + 8740531 = 8740578
59 + 8740519 = 8740578
61 + 8740517 = 8740578
131 + 8740447 = 8740578
149 + 8740429 = 8740578

Showing the first eight; more decompositions exist.
