Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998220, here are decompositions:

7 + 998213 = 998220
19 + 998201 = 998220
23 + 998197 = 998220
53 + 998167 = 998220
59 + 998161 = 998220
73 + 998147 = 998220
103 + 998117 = 998220
109 + 998111 = 998220

Showing the first eight; more decompositions exist.
