Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 999222, here are decompositions:

5 + 999217 = 999222
23 + 999199 = 999222
41 + 999181 = 999222
53 + 999169 = 999222
73 + 999149 = 999222
89 + 999133 = 999222
131 + 999091 = 999222
139 + 999083 = 999222

Showing the first eight; more decompositions exist.
