Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542856, here are decompositions:
- 29 + 31542827 = 31542856
- 47 + 31542809 = 31542856
- 89 + 31542767 = 31542856
- 179 + 31542677 = 31542856
- 197 + 31542659 = 31542856
- 269 + 31542587 = 31542856
- 347 + 31542509 = 31542856
- 419 + 31542437 = 31542856
Showing the first eight; more decompositions exist.
