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.
