Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542684, here are decompositions:
- 7 + 31542677 = 31542684
- 53 + 31542631 = 31542684
- 71 + 31542613 = 31542684
- 97 + 31542587 = 31542684
- 137 + 31542547 = 31542684
- 197 + 31542487 = 31542684
- 227 + 31542457 = 31542684
- 293 + 31542391 = 31542684
Showing the first eight; more decompositions exist.
