Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545538, here are decompositions:
- 131 + 31545407 = 31545538
- 137 + 31545401 = 31545538
- 239 + 31545299 = 31545538
- 251 + 31545287 = 31545538
- 317 + 31545221 = 31545538
- 347 + 31545191 = 31545538
- 419 + 31545119 = 31545538
- 569 + 31544969 = 31545538
Showing the first eight; more decompositions exist.
