Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722442, here are decompositions:

13 + 8722429 = 8722442
19 + 8722423 = 8722442
103 + 8722339 = 8722442
109 + 8722333 = 8722442
139 + 8722303 = 8722442
151 + 8722291 = 8722442
271 + 8722171 = 8722442
349 + 8722093 = 8722442

Showing the first eight; more decompositions exist.
