Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 988432, here are decompositions:

23 + 988409 = 988432
89 + 988343 = 988432
113 + 988319 = 988432
233 + 988199 = 988432
449 + 987983 = 988432
461 + 987971 = 988432
491 + 987941 = 988432
503 + 987929 = 988432

Showing the first eight; more decompositions exist.
