Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542788, here are decompositions:
- 61 + 31542727 = 31542788
- 157 + 31542631 = 31542788
- 229 + 31542559 = 31542788
- 241 + 31542547 = 31542788
- 331 + 31542457 = 31542788
- 349 + 31542439 = 31542788
- 397 + 31542391 = 31542788
- 751 + 31542037 = 31542788
Showing the first eight; more decompositions exist.
