Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 67138, here are decompositions:
- 17 + 67121 = 67138
- 59 + 67079 = 67138
- 89 + 67049 = 67138
- 179 + 66959 = 67138
- 191 + 66947 = 67138
- 317 + 66821 = 67138
- 347 + 66791 = 67138
- 389 + 66749 = 67138
Showing the first eight; more decompositions exist.
