Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 988828, here are decompositions:

101 + 988727 = 988828
167 + 988661 = 988828
179 + 988649 = 988828
251 + 988577 = 988828
257 + 988571 = 988828
317 + 988511 = 988828
389 + 988439 = 988828
419 + 988409 = 988828

Showing the first eight; more decompositions exist.
