Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 67280, here are decompositions:
- 7 + 67273 = 67280
- 19 + 67261 = 67280
- 61 + 67219 = 67280
- 67 + 67213 = 67280
- 127 + 67153 = 67280
- 139 + 67141 = 67280
- 151 + 67129 = 67280
- 223 + 67057 = 67280
Showing the first eight; more decompositions exist.
