Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722452, here are decompositions:

5 + 8722447 = 8722452
23 + 8722429 = 8722452
29 + 8722423 = 8722452
43 + 8722409 = 8722452
59 + 8722393 = 8722452
61 + 8722391 = 8722452
113 + 8722339 = 8722452
149 + 8722303 = 8722452

Showing the first eight; more decompositions exist.
