Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31538934, here are decompositions:
- 47 + 31538887 = 31538934
- 107 + 31538827 = 31538934
- 127 + 31538807 = 31538934
- 181 + 31538753 = 31538934
- 191 + 31538743 = 31538934
- 223 + 31538711 = 31538934
- 241 + 31538693 = 31538934
- 263 + 31538671 = 31538934
Showing the first eight; more decompositions exist.
