Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545342, here are decompositions:
- 11 + 31545331 = 31545342
- 13 + 31545329 = 31545342
- 19 + 31545323 = 31545342
- 43 + 31545299 = 31545342
- 109 + 31545233 = 31545342
- 131 + 31545211 = 31545342
- 151 + 31545191 = 31545342
- 223 + 31545119 = 31545342
Showing the first eight; more decompositions exist.
