Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990936, here are decompositions:

13 + 990923 = 990936
19 + 990917 = 990936
43 + 990893 = 990936
47 + 990889 = 990936
127 + 990809 = 990936
137 + 990799 = 990936
139 + 990797 = 990936
229 + 990707 = 990936

Showing the first eight; more decompositions exist.
