Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 988906, here are decompositions:

5 + 988901 = 988906
29 + 988877 = 988906
47 + 988859 = 988906
173 + 988733 = 988906
179 + 988727 = 988906
257 + 988649 = 988906
263 + 988643 = 988906
467 + 988439 = 988906

Showing the first eight; more decompositions exist.
