Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990856, here are decompositions:

5 + 990851 = 990856
47 + 990809 = 990856
59 + 990797 = 990856
89 + 990767 = 990856
137 + 990719 = 990856
149 + 990707 = 990856
257 + 990599 = 990856
263 + 990593 = 990856

Showing the first eight; more decompositions exist.
