Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544312, here are decompositions:
- 31 + 31544281 = 31544312
- 181 + 31544131 = 31544312
- 223 + 31544089 = 31544312
- 271 + 31544041 = 31544312
- 409 + 31543903 = 31544312
- 439 + 31543873 = 31544312
- 601 + 31543711 = 31544312
- 643 + 31543669 = 31544312
Showing the first eight; more decompositions exist.
