Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78112, here are decompositions:
- 11 + 78101 = 78112
- 53 + 78059 = 78112
- 71 + 78041 = 78112
- 113 + 77999 = 78112
- 179 + 77933 = 78112
- 263 + 77849 = 78112
- 311 + 77801 = 78112
- 389 + 77723 = 78112
Showing the first eight; more decompositions exist.
