Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537744, here are decompositions:
- 3 + 31537741 = 31537744
- 23 + 31537721 = 31537744
- 53 + 31537691 = 31537744
- 113 + 31537631 = 31537744
- 197 + 31537547 = 31537744
- 263 + 31537481 = 31537744
- 311 + 31537433 = 31537744
- 353 + 31537391 = 31537744
Showing the first eight; more decompositions exist.
