Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990532, here are decompositions:

3 + 990529 = 990532
29 + 990503 = 990532
149 + 990383 = 990532
173 + 990359 = 990532
239 + 990293 = 990532
251 + 990281 = 990532
293 + 990239 = 990532
353 + 990179 = 990532

Showing the first eight; more decompositions exist.
