Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78266, here are decompositions:
- 7 + 78259 = 78266
- 37 + 78229 = 78266
- 73 + 78193 = 78266
- 103 + 78163 = 78266
- 109 + 78157 = 78266
- 127 + 78139 = 78266
- 283 + 77983 = 78266
- 337 + 77929 = 78266
Showing the first eight; more decompositions exist.
