Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 988558, here are decompositions:

17 + 988541 = 988558
47 + 988511 = 988558
149 + 988409 = 988558
191 + 988367 = 988558
239 + 988319 = 988558
359 + 988199 = 988558
401 + 988157 = 988558
449 + 988109 = 988558

Showing the first eight; more decompositions exist.
