Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534336, here are decompositions:
- 3 + 31534333 = 31534336
- 89 + 31534247 = 31534336
- 137 + 31534199 = 31534336
- 149 + 31534187 = 31534336
- 167 + 31534169 = 31534336
- 233 + 31534103 = 31534336
- 257 + 31534079 = 31534336
- 263 + 31534073 = 31534336
Showing the first eight; more decompositions exist.
