Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990732, here are decompositions:

13 + 990719 = 990732
59 + 990673 = 990732
89 + 990643 = 990732
101 + 990631 = 990732
139 + 990593 = 990732
173 + 990559 = 990732
229 + 990503 = 990732
263 + 990469 = 990732

Showing the first eight; more decompositions exist.
