Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990926, here are decompositions:

3 + 990923 = 990926
37 + 990889 = 990926
127 + 990799 = 990926
193 + 990733 = 990926
283 + 990643 = 990926
337 + 990589 = 990926
367 + 990559 = 990926
379 + 990547 = 990926

Showing the first eight; more decompositions exist.
