Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 69872, here are decompositions:
- 13 + 69859 = 69872
- 43 + 69829 = 69872
- 109 + 69763 = 69872
- 163 + 69709 = 69872
- 181 + 69691 = 69872
- 211 + 69661 = 69872
- 373 + 69499 = 69872
- 379 + 69493 = 69872
Showing the first eight; more decompositions exist.
