Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 989818, here are decompositions:

41 + 989777 = 989818
131 + 989687 = 989818
239 + 989579 = 989818
257 + 989561 = 989818
311 + 989507 = 989818
491 + 989327 = 989818
509 + 989309 = 989818
569 + 989249 = 989818

Showing the first eight; more decompositions exist.
