Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78142, here are decompositions:
- 3 + 78139 = 78142
- 5 + 78137 = 78142
- 41 + 78101 = 78142
- 83 + 78059 = 78142
- 101 + 78041 = 78142
- 173 + 77969 = 78142
- 191 + 77951 = 78142
- 293 + 77849 = 78142
Showing the first eight; more decompositions exist.
