Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 67742, here are decompositions:
- 19 + 67723 = 67742
- 43 + 67699 = 67742
- 163 + 67579 = 67742
- 211 + 67531 = 67742
- 313 + 67429 = 67742
- 331 + 67411 = 67742
- 373 + 67369 = 67742
- 523 + 67219 = 67742
Showing the first eight; more decompositions exist.
