Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545382, here are decompositions:
- 3 + 31545379 = 31545382
- 53 + 31545329 = 31545382
- 59 + 31545323 = 31545382
- 83 + 31545299 = 31545382
- 149 + 31545233 = 31545382
- 191 + 31545191 = 31545382
- 263 + 31545119 = 31545382
- 359 + 31545023 = 31545382
Showing the first eight; more decompositions exist.
