Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 988870, here are decompositions:

11 + 988859 = 988870
41 + 988829 = 988870
107 + 988763 = 988870
137 + 988733 = 988870
227 + 988643 = 988870
263 + 988607 = 988870
293 + 988577 = 988870
359 + 988511 = 988870

Showing the first eight; more decompositions exist.
