Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 68100, here are decompositions:
- 13 + 68087 = 68100
- 29 + 68071 = 68100
- 41 + 68059 = 68100
- 47 + 68053 = 68100
- 59 + 68041 = 68100
- 107 + 67993 = 68100
- 113 + 67987 = 68100
- 139 + 67961 = 68100
Showing the first eight; more decompositions exist.
