Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990740, here are decompositions:

7 + 990733 = 990740
67 + 990673 = 990740
97 + 990643 = 990740
103 + 990637 = 990740
109 + 990631 = 990740
151 + 990589 = 990740
181 + 990559 = 990740
193 + 990547 = 990740

Showing the first eight; more decompositions exist.
