Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80938, here are decompositions:
- 5 + 80933 = 80938
- 29 + 80909 = 80938
- 41 + 80897 = 80938
- 89 + 80849 = 80938
- 107 + 80831 = 80938
- 149 + 80789 = 80938
- 191 + 80747 = 80938
- 251 + 80687 = 80938
Showing the first eight; more decompositions exist.
