Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72828, here are decompositions:
- 5 + 72823 = 72828
- 11 + 72817 = 72828
- 31 + 72797 = 72828
- 61 + 72767 = 72828
- 89 + 72739 = 72828
- 101 + 72727 = 72828
- 109 + 72719 = 72828
- 127 + 72701 = 72828
Showing the first eight; more decompositions exist.
