Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 68124, here are decompositions:
- 11 + 68113 = 68124
- 13 + 68111 = 68124
- 37 + 68087 = 68124
- 53 + 68071 = 68124
- 71 + 68053 = 68124
- 83 + 68041 = 68124
- 101 + 68023 = 68124
- 131 + 67993 = 68124
Showing the first eight; more decompositions exist.
