Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80878, here are decompositions:
- 29 + 80849 = 80878
- 47 + 80831 = 80878
- 59 + 80819 = 80878
- 89 + 80789 = 80878
- 101 + 80777 = 80878
- 131 + 80747 = 80878
- 191 + 80687 = 80878
- 197 + 80681 = 80878
Showing the first eight; more decompositions exist.
