Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 67138, here are decompositions:

17 + 67121 = 67138
59 + 67079 = 67138
89 + 67049 = 67138
179 + 66959 = 67138
191 + 66947 = 67138
317 + 66821 = 67138
347 + 66791 = 67138
389 + 66749 = 67138

Showing the first eight; more decompositions exist.
