Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78904, here are decompositions:
- 3 + 78901 = 78904
- 11 + 78893 = 78904
- 17 + 78887 = 78904
- 47 + 78857 = 78904
- 101 + 78803 = 78904
- 107 + 78797 = 78904
- 113 + 78791 = 78904
- 167 + 78737 = 78904
Showing the first eight; more decompositions exist.
