Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 68542, here are decompositions:
- 3 + 68539 = 68542
- 11 + 68531 = 68542
- 41 + 68501 = 68542
- 53 + 68489 = 68542
- 59 + 68483 = 68542
- 191 + 68351 = 68542
- 263 + 68279 = 68542
- 281 + 68261 = 68542
Showing the first eight; more decompositions exist.
