Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 988426, here are decompositions:

17 + 988409 = 988426
59 + 988367 = 988426
83 + 988343 = 988426
107 + 988319 = 988426
113 + 988313 = 988426
227 + 988199 = 988426
269 + 988157 = 988426
317 + 988109 = 988426

Showing the first eight; more decompositions exist.
