Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78192, here are decompositions:
- 13 + 78179 = 78192
- 19 + 78173 = 78192
- 29 + 78163 = 78192
- 53 + 78139 = 78192
- 71 + 78121 = 78192
- 113 + 78079 = 78192
- 151 + 78041 = 78192
- 193 + 77999 = 78192
Showing the first eight; more decompositions exist.
