Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990196, here are decompositions:

17 + 990179 = 990196
59 + 990137 = 990196
173 + 990023 = 990196
197 + 989999 = 990196
257 + 989939 = 990196
359 + 989837 = 990196
419 + 989777 = 990196
443 + 989753 = 990196

Showing the first eight; more decompositions exist.
