Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722338, here are decompositions:

5 + 8722333 = 8722338
7 + 8722331 = 8722338
41 + 8722297 = 8722338
47 + 8722291 = 8722338
101 + 8722237 = 8722338
127 + 8722211 = 8722338
151 + 8722187 = 8722338
167 + 8722171 = 8722338

Showing the first eight; more decompositions exist.
