Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 989644, here are decompositions:

3 + 989641 = 989644
83 + 989561 = 989644
137 + 989507 = 989644
167 + 989477 = 989644
233 + 989411 = 989644
263 + 989381 = 989644
317 + 989327 = 989644
521 + 989123 = 989644

Showing the first eight; more decompositions exist.
