Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645454, here are decompositions:

5 + 8645449 = 8645454
11 + 8645443 = 8645454
23 + 8645431 = 8645454
47 + 8645407 = 8645454
73 + 8645381 = 8645454
101 + 8645353 = 8645454
113 + 8645341 = 8645454
127 + 8645327 = 8645454

Showing the first eight; more decompositions exist.
