Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 989442, here are decompositions:

19 + 989423 = 989442
23 + 989419 = 989442
31 + 989411 = 989442
61 + 989381 = 989442
89 + 989353 = 989442
101 + 989341 = 989442
149 + 989293 = 989442
163 + 989279 = 989442

Showing the first eight; more decompositions exist.
