Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 989142, here are decompositions:

19 + 989123 = 989142
23 + 989119 = 989142
43 + 989099 = 989142
61 + 989081 = 989142
71 + 989071 = 989142
83 + 989059 = 989142
113 + 989029 = 989142
131 + 989011 = 989142

Showing the first eight; more decompositions exist.
