Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 988636, here are decompositions:

29 + 988607 = 988636
53 + 988583 = 988636
59 + 988577 = 988636
197 + 988439 = 988636
227 + 988409 = 988636
269 + 988367 = 988636
293 + 988343 = 988636
317 + 988319 = 988636

Showing the first eight; more decompositions exist.
