Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 83138, here are decompositions:

37 + 83101 = 83138
61 + 83077 = 83138
67 + 83071 = 83138
79 + 83059 = 83138
157 + 82981 = 83138
199 + 82939 = 83138
379 + 82759 = 83138
409 + 82729 = 83138

Showing the first eight; more decompositions exist.
