Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718450, here are decompositions:

11 + 8718439 = 8718450
19 + 8718431 = 8718450
23 + 8718427 = 8718450
31 + 8718419 = 8718450
43 + 8718407 = 8718450
73 + 8718377 = 8718450
101 + 8718349 = 8718450
107 + 8718343 = 8718450

Showing the first eight; more decompositions exist.
