Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 68872, here are decompositions:
- 53 + 68819 = 68872
- 59 + 68813 = 68872
- 101 + 68771 = 68872
- 173 + 68699 = 68872
- 233 + 68639 = 68872
- 239 + 68633 = 68872
- 383 + 68489 = 68872
- 389 + 68483 = 68872
Showing the first eight; more decompositions exist.
