Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8664222, here are decompositions:

29 + 8664193 = 8664222
41 + 8664181 = 8664222
113 + 8664109 = 8664222
179 + 8664043 = 8664222
199 + 8664023 = 8664222
263 + 8663959 = 8664222
353 + 8663869 = 8664222
401 + 8663821 = 8664222

Showing the first eight; more decompositions exist.
