Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541856, here are decompositions:
- 29 + 31541827 = 31541856
- 149 + 31541707 = 31541856
- 163 + 31541693 = 31541856
- 179 + 31541677 = 31541856
- 197 + 31541659 = 31541856
- 223 + 31541633 = 31541856
- 293 + 31541563 = 31541856
- 347 + 31541509 = 31541856
Showing the first eight; more decompositions exist.
