Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 84040, here are decompositions:

23 + 84017 = 84040
29 + 84011 = 84040
53 + 83987 = 84040
71 + 83969 = 84040
101 + 83939 = 84040
107 + 83933 = 84040
137 + 83903 = 84040
149 + 83891 = 84040

Showing the first eight; more decompositions exist.
