Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990202, here are decompositions:

23 + 990179 = 990202
149 + 990053 = 990202
179 + 990023 = 990202
251 + 989951 = 990202
263 + 989939 = 990202
281 + 989921 = 990202
293 + 989909 = 990202
419 + 989783 = 990202

Showing the first eight; more decompositions exist.
