Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 68160, here are decompositions:
- 13 + 68147 = 68160
- 19 + 68141 = 68160
- 47 + 68113 = 68160
- 61 + 68099 = 68160
- 73 + 68087 = 68160
- 89 + 68071 = 68160
- 101 + 68059 = 68160
- 107 + 68053 = 68160
Showing the first eight; more decompositions exist.
