Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 67142, here are decompositions:
- 3 + 67139 = 67142
- 13 + 67129 = 67142
- 109 + 67033 = 67142
- 139 + 67003 = 67142
- 193 + 66949 = 67142
- 199 + 66943 = 67142
- 211 + 66931 = 67142
- 223 + 66919 = 67142
Showing the first eight; more decompositions exist.
