Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 989538, here are decompositions:

5 + 989533 = 989538
31 + 989507 = 989538
59 + 989479 = 989538
61 + 989477 = 989538
71 + 989467 = 989538
97 + 989441 = 989538
127 + 989411 = 989538
157 + 989381 = 989538

Showing the first eight; more decompositions exist.
