Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78242, here are decompositions:
- 13 + 78229 = 78242
- 79 + 78163 = 78242
- 103 + 78139 = 78242
- 163 + 78079 = 78242
- 193 + 78049 = 78242
- 211 + 78031 = 78242
- 313 + 77929 = 78242
- 349 + 77893 = 78242
Showing the first eight; more decompositions exist.
