Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998226, here are decompositions:

7 + 998219 = 998226
13 + 998213 = 998226
29 + 998197 = 998226
59 + 998167 = 998226
79 + 998147 = 998226
109 + 998117 = 998226
149 + 998077 = 998226
157 + 998069 = 998226

Showing the first eight; more decompositions exist.
