Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8740424, here are decompositions:

13 + 8740411 = 8740424
31 + 8740393 = 8740424
37 + 8740387 = 8740424
97 + 8740327 = 8740424
103 + 8740321 = 8740424
151 + 8740273 = 8740424
241 + 8740183 = 8740424
307 + 8740117 = 8740424

Showing the first eight; more decompositions exist.
