Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78386, here are decompositions:
- 19 + 78367 = 78386
- 79 + 78307 = 78386
- 103 + 78283 = 78386
- 109 + 78277 = 78386
- 127 + 78259 = 78386
- 157 + 78229 = 78386
- 193 + 78193 = 78386
- 223 + 78163 = 78386
Showing the first eight; more decompositions exist.
