Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78104, here are decompositions:
- 3 + 78101 = 78104
- 73 + 78031 = 78104
- 97 + 78007 = 78104
- 127 + 77977 = 78104
- 211 + 77893 = 78104
- 241 + 77863 = 78104
- 307 + 77797 = 78104
- 331 + 77773 = 78104
Showing the first eight; more decompositions exist.
