Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 989992, here are decompositions:

11 + 989981 = 989992
41 + 989951 = 989992
53 + 989939 = 989992
71 + 989921 = 989992
83 + 989909 = 989992
239 + 989753 = 989992
431 + 989561 = 989992
569 + 989423 = 989992

Showing the first eight; more decompositions exist.
