Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 74138, here are decompositions:

7 + 74131 = 74138
37 + 74101 = 74138
61 + 74077 = 74138
67 + 74071 = 74138
139 + 73999 = 74138
199 + 73939 = 74138
241 + 73897 = 74138
271 + 73867 = 74138

Showing the first eight; more decompositions exist.
