Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 989620, here are decompositions:

41 + 989579 = 989620
59 + 989561 = 989620
113 + 989507 = 989620
179 + 989441 = 989620
197 + 989423 = 989620
239 + 989381 = 989620
293 + 989327 = 989620
311 + 989309 = 989620

Showing the first eight; more decompositions exist.
