Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80872, here are decompositions:
- 23 + 80849 = 80872
- 41 + 80831 = 80872
- 53 + 80819 = 80872
- 83 + 80789 = 80872
- 89 + 80783 = 80872
- 191 + 80681 = 80872
- 251 + 80621 = 80872
- 269 + 80603 = 80872
Showing the first eight; more decompositions exist.
