Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 68870, here are decompositions:
- 7 + 68863 = 68870
- 79 + 68791 = 68870
- 103 + 68767 = 68870
- 127 + 68743 = 68870
- 157 + 68713 = 68870
- 211 + 68659 = 68870
- 331 + 68539 = 68870
- 349 + 68521 = 68870
Showing the first eight; more decompositions exist.
