Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31412, here are decompositions:
- 19 + 31393 = 31412
- 79 + 31333 = 31412
- 163 + 31249 = 31412
- 181 + 31231 = 31412
- 193 + 31219 = 31412
- 223 + 31189 = 31412
- 229 + 31183 = 31412
- 331 + 31081 = 31412
Showing the first eight; more decompositions exist.
