Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 83158, here are decompositions:
- 41 + 83117 = 83158
- 149 + 83009 = 83158
- 269 + 82889 = 83158
- 311 + 82847 = 83158
- 347 + 82811 = 83158
- 359 + 82799 = 83158
- 401 + 82757 = 83158
- 431 + 82727 = 83158
Showing the first eight; more decompositions exist.
