Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534216, here are decompositions:
- 17 + 31534199 = 31534216
- 29 + 31534187 = 31534216
- 47 + 31534169 = 31534216
- 113 + 31534103 = 31534216
- 137 + 31534079 = 31534216
- 149 + 31534067 = 31534216
- 257 + 31533959 = 31534216
- 293 + 31533923 = 31534216
Showing the first eight; more decompositions exist.
