Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990752, here are decompositions:

19 + 990733 = 990752
79 + 990673 = 990752
109 + 990643 = 990752
163 + 990589 = 990752
193 + 990559 = 990752
223 + 990529 = 990752
229 + 990523 = 990752
241 + 990511 = 990752

Showing the first eight; more decompositions exist.
