Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 989290, here are decompositions:

11 + 989279 = 989290
41 + 989249 = 989290
59 + 989231 = 989290
167 + 989123 = 989290
191 + 989099 = 989290
311 + 988979 = 989290
353 + 988937 = 989290
389 + 988901 = 989290

Showing the first eight; more decompositions exist.
