Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 989390, here are decompositions:

13 + 989377 = 989390
37 + 989353 = 989390
43 + 989347 = 989390
67 + 989323 = 989390
97 + 989293 = 989390
139 + 989251 = 989390
151 + 989239 = 989390
271 + 989119 = 989390

Showing the first eight; more decompositions exist.
