Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 68242, here are decompositions:
- 3 + 68239 = 68242
- 23 + 68219 = 68242
- 29 + 68213 = 68242
- 71 + 68171 = 68242
- 101 + 68141 = 68242
- 131 + 68111 = 68242
- 263 + 67979 = 68242
- 281 + 67961 = 68242
Showing the first eight; more decompositions exist.
