Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8740428, here are decompositions:

17 + 8740411 = 8740428
41 + 8740387 = 8740428
61 + 8740367 = 8740428
97 + 8740331 = 8740428
101 + 8740327 = 8740428
107 + 8740321 = 8740428
127 + 8740301 = 8740428
139 + 8740289 = 8740428

Showing the first eight; more decompositions exist.
