Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543466, here are decompositions:
- 13 + 31543453 = 31543466
- 37 + 31543429 = 31543466
- 193 + 31543273 = 31543466
- 223 + 31543243 = 31543466
- 397 + 31543069 = 31543466
- 457 + 31543009 = 31543466
- 499 + 31542967 = 31543466
- 523 + 31542943 = 31543466
Showing the first eight; more decompositions exist.
