Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 67290, here are decompositions:
- 17 + 67273 = 67290
- 19 + 67271 = 67290
- 29 + 67261 = 67290
- 43 + 67247 = 67290
- 59 + 67231 = 67290
- 71 + 67219 = 67290
- 73 + 67217 = 67290
- 79 + 67211 = 67290
Showing the first eight; more decompositions exist.
