Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 68142, here are decompositions:
- 29 + 68113 = 68142
- 31 + 68111 = 68142
- 43 + 68099 = 68142
- 71 + 68071 = 68142
- 83 + 68059 = 68142
- 89 + 68053 = 68142
- 101 + 68041 = 68142
- 149 + 67993 = 68142
Showing the first eight; more decompositions exist.
