Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78156, here are decompositions:
- 17 + 78139 = 78156
- 19 + 78137 = 78156
- 97 + 78059 = 78156
- 107 + 78049 = 78156
- 139 + 78017 = 78156
- 149 + 78007 = 78156
- 157 + 77999 = 78156
- 173 + 77983 = 78156
Showing the first eight; more decompositions exist.
