Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 68972, here are decompositions:
- 73 + 68899 = 68972
- 109 + 68863 = 68972
- 151 + 68821 = 68972
- 181 + 68791 = 68972
- 223 + 68749 = 68972
- 229 + 68743 = 68972
- 313 + 68659 = 68972
- 433 + 68539 = 68972
Showing the first eight; more decompositions exist.
