Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990854, here are decompositions:

3 + 990851 = 990854
13 + 990841 = 990854
181 + 990673 = 990854
211 + 990643 = 990854
223 + 990631 = 990854
307 + 990547 = 990854
331 + 990523 = 990854
367 + 990487 = 990854

Showing the first eight; more decompositions exist.
