Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8654478, here are decompositions:

11 + 8654467 = 8654478
17 + 8654461 = 8654478
31 + 8654447 = 8654478
47 + 8654431 = 8654478
89 + 8654389 = 8654478
97 + 8654381 = 8654478
127 + 8654351 = 8654478
139 + 8654339 = 8654478

Showing the first eight; more decompositions exist.
