Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 989672, here are decompositions:

31 + 989641 = 989672
43 + 989629 = 989672
139 + 989533 = 989672
193 + 989479 = 989672
331 + 989341 = 989672
349 + 989323 = 989672
379 + 989293 = 989672
421 + 989251 = 989672

Showing the first eight; more decompositions exist.
