Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8740530, here are decompositions:

11 + 8740519 = 8740530
13 + 8740517 = 8740530
37 + 8740493 = 8740530
83 + 8740447 = 8740530
101 + 8740429 = 8740530
103 + 8740427 = 8740530
137 + 8740393 = 8740530
157 + 8740373 = 8740530

Showing the first eight; more decompositions exist.
