Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545904, here are decompositions:
- 3 + 31545901 = 31545904
- 17 + 31545887 = 31545904
- 167 + 31545737 = 31545904
- 191 + 31545713 = 31545904
- 263 + 31545641 = 31545904
- 281 + 31545623 = 31545904
- 293 + 31545611 = 31545904
- 503 + 31545401 = 31545904
Showing the first eight; more decompositions exist.
