Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80804, here are decompositions:
- 43 + 80761 = 80804
- 67 + 80737 = 80804
- 103 + 80701 = 80804
- 127 + 80677 = 80804
- 193 + 80611 = 80804
- 277 + 80527 = 80804
- 313 + 80491 = 80804
- 331 + 80473 = 80804
Showing the first eight; more decompositions exist.
