Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542740, here are decompositions:
- 13 + 31542727 = 31542740
- 37 + 31542703 = 31542740
- 43 + 31542697 = 31542740
- 109 + 31542631 = 31542740
- 127 + 31542613 = 31542740
- 181 + 31542559 = 31542740
- 193 + 31542547 = 31542740
- 283 + 31542457 = 31542740
Showing the first eight; more decompositions exist.
