Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545936, here are decompositions:
- 13 + 31545923 = 31545936
- 17 + 31545919 = 31545936
- 173 + 31545763 = 31545936
- 193 + 31545743 = 31545936
- 197 + 31545739 = 31545936
- 199 + 31545737 = 31545936
- 223 + 31545713 = 31545936
- 269 + 31545667 = 31545936
Showing the first eight; more decompositions exist.
