Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545436, here are decompositions:
- 29 + 31545407 = 31545436
- 107 + 31545329 = 31545436
- 113 + 31545323 = 31545436
- 137 + 31545299 = 31545436
- 149 + 31545287 = 31545436
- 317 + 31545119 = 31545436
- 353 + 31545083 = 31545436
- 467 + 31544969 = 31545436
Showing the first eight; more decompositions exist.
