Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 988840, here are decompositions:

3 + 988837 = 988840
11 + 988829 = 988840
107 + 988733 = 988840
113 + 988727 = 988840
179 + 988661 = 988840
191 + 988649 = 988840
197 + 988643 = 988840
233 + 988607 = 988840

Showing the first eight; more decompositions exist.
