Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990472, here are decompositions:

3 + 990469 = 990472
83 + 990389 = 990472
89 + 990383 = 990472
101 + 990371 = 990472
113 + 990359 = 990472
149 + 990323 = 990472
179 + 990293 = 990472
191 + 990281 = 990472

Showing the first eight; more decompositions exist.
