Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 68268, here are decompositions:
- 7 + 68261 = 68268
- 29 + 68239 = 68268
- 41 + 68227 = 68268
- 59 + 68209 = 68268
- 61 + 68207 = 68268
- 97 + 68171 = 68268
- 107 + 68161 = 68268
- 127 + 68141 = 68268
Showing the first eight; more decompositions exist.
