Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 67538, here are decompositions:

7 + 67531 = 67538
61 + 67477 = 67538
109 + 67429 = 67538
127 + 67411 = 67538
139 + 67399 = 67538
199 + 67339 = 67538
277 + 67261 = 67538
307 + 67231 = 67538

Showing the first eight; more decompositions exist.
