Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722212, here are decompositions:

19 + 8722193 = 8722212
41 + 8722171 = 8722212
43 + 8722169 = 8722212
89 + 8722123 = 8722212
113 + 8722099 = 8722212
131 + 8722081 = 8722212
179 + 8722033 = 8722212
193 + 8722019 = 8722212

Showing the first eight; more decompositions exist.
