Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722380, here are decompositions:

13 + 8722367 = 8722380
19 + 8722361 = 8722380
41 + 8722339 = 8722380
47 + 8722333 = 8722380
83 + 8722297 = 8722380
89 + 8722291 = 8722380
97 + 8722283 = 8722380
157 + 8722223 = 8722380

Showing the first eight; more decompositions exist.
