Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78206, here are decompositions:
- 3 + 78203 = 78206
- 13 + 78193 = 78206
- 43 + 78163 = 78206
- 67 + 78139 = 78206
- 127 + 78079 = 78206
- 157 + 78049 = 78206
- 199 + 78007 = 78206
- 223 + 77983 = 78206
Showing the first eight; more decompositions exist.
