Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 989558, here are decompositions:

79 + 989479 = 989558
139 + 989419 = 989558
181 + 989377 = 989558
211 + 989347 = 989558
307 + 989251 = 989558
439 + 989119 = 989558
487 + 989071 = 989558
499 + 989059 = 989558

Showing the first eight; more decompositions exist.
