Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 74128, here are decompositions:
- 29 + 74099 = 74128
- 101 + 74027 = 74128
- 107 + 74021 = 74128
- 167 + 73961 = 74128
- 251 + 73877 = 74128
- 269 + 73859 = 74128
- 281 + 73847 = 74128
- 401 + 73727 = 74128
Showing the first eight; more decompositions exist.
