Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80904, here are decompositions:
- 7 + 80897 = 80904
- 41 + 80863 = 80904
- 71 + 80833 = 80904
- 73 + 80831 = 80904
- 101 + 80803 = 80904
- 127 + 80777 = 80904
- 157 + 80747 = 80904
- 167 + 80737 = 80904
Showing the first eight; more decompositions exist.
