Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722434, here are decompositions:

5 + 8722429 = 8722434
11 + 8722423 = 8722434
41 + 8722393 = 8722434
43 + 8722391 = 8722434
67 + 8722367 = 8722434
73 + 8722361 = 8722434
101 + 8722333 = 8722434
103 + 8722331 = 8722434

Showing the first eight; more decompositions exist.
