Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 989742, here are decompositions:

23 + 989719 = 989742
71 + 989671 = 989742
79 + 989663 = 989742
101 + 989641 = 989742
113 + 989629 = 989742
163 + 989579 = 989742
181 + 989561 = 989742
263 + 989479 = 989742

Showing the first eight; more decompositions exist.
