Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31538016, here are decompositions:
- 17 + 31537999 = 31538016
- 19 + 31537997 = 31538016
- 113 + 31537903 = 31538016
- 127 + 31537889 = 31538016
- 157 + 31537859 = 31538016
- 173 + 31537843 = 31538016
- 179 + 31537837 = 31538016
- 193 + 31537823 = 31538016
Showing the first eight; more decompositions exist.
