Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990814, here are decompositions:

5 + 990809 = 990814
17 + 990797 = 990814
47 + 990767 = 990814
53 + 990761 = 990814
107 + 990707 = 990814
311 + 990503 = 990814
317 + 990497 = 990814
431 + 990383 = 990814

Showing the first eight; more decompositions exist.
