Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545112, here are decompositions:
- 29 + 31545083 = 31545112
- 89 + 31545023 = 31545112
- 149 + 31544963 = 31545112
- 233 + 31544879 = 31545112
- 293 + 31544819 = 31545112
- 353 + 31544759 = 31545112
- 569 + 31544543 = 31545112
- 719 + 31544393 = 31545112
Showing the first eight; more decompositions exist.
