Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 83128, here are decompositions:
- 11 + 83117 = 83128
- 131 + 82997 = 83128
- 239 + 82889 = 83128
- 281 + 82847 = 83128
- 317 + 82811 = 83128
- 347 + 82781 = 83128
- 401 + 82727 = 83128
- 509 + 82619 = 83128
Showing the first eight; more decompositions exist.
