Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78118, here are decompositions:
- 17 + 78101 = 78118
- 59 + 78059 = 78118
- 101 + 78017 = 78118
- 149 + 77969 = 78118
- 167 + 77951 = 78118
- 251 + 77867 = 78118
- 269 + 77849 = 78118
- 317 + 77801 = 78118
Showing the first eight; more decompositions exist.
