Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 988918, here are decompositions:

17 + 988901 = 988918
41 + 988877 = 988918
59 + 988859 = 988918
89 + 988829 = 988918
191 + 988727 = 988918
257 + 988661 = 988918
269 + 988649 = 988918
311 + 988607 = 988918

Showing the first eight; more decompositions exist.
