Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987042, here are decompositions:

13 + 987029 = 987042
19 + 987023 = 987042
29 + 987013 = 987042
53 + 986989 = 987042
59 + 986983 = 987042
61 + 986981 = 987042
79 + 986963 = 987042
83 + 986959 = 987042

Showing the first eight; more decompositions exist.
