Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 84138, here are decompositions:

7 + 84131 = 84138
11 + 84127 = 84138
17 + 84121 = 84138
71 + 84067 = 84138
79 + 84059 = 84138
127 + 84011 = 84138
151 + 83987 = 84138
199 + 83939 = 84138

Showing the first eight; more decompositions exist.
