Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80890, here are decompositions:
- 41 + 80849 = 80890
- 59 + 80831 = 80890
- 71 + 80819 = 80890
- 101 + 80789 = 80890
- 107 + 80783 = 80890
- 113 + 80777 = 80890
- 233 + 80657 = 80890
- 239 + 80651 = 80890
Showing the first eight; more decompositions exist.
