Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80726, here are decompositions:
- 13 + 80713 = 80726
- 43 + 80683 = 80726
- 97 + 80629 = 80726
- 127 + 80599 = 80726
- 199 + 80527 = 80726
- 277 + 80449 = 80726
- 379 + 80347 = 80726
- 397 + 80329 = 80726
Showing the first eight; more decompositions exist.
