Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543952, here are decompositions:
- 79 + 31543873 = 31543952
- 109 + 31543843 = 31543952
- 229 + 31543723 = 31543952
- 241 + 31543711 = 31543952
- 283 + 31543669 = 31543952
- 373 + 31543579 = 31543952
- 409 + 31543543 = 31543952
- 421 + 31543531 = 31543952
Showing the first eight; more decompositions exist.
