Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 67400, here are decompositions:
- 31 + 67369 = 67400
- 61 + 67339 = 67400
- 127 + 67273 = 67400
- 139 + 67261 = 67400
- 181 + 67219 = 67400
- 211 + 67189 = 67400
- 271 + 67129 = 67400
- 367 + 67033 = 67400
Showing the first eight; more decompositions exist.
