Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543368, here are decompositions:
- 7 + 31543361 = 31543368
- 19 + 31543349 = 31543368
- 37 + 31543331 = 31543368
- 67 + 31543301 = 31543368
- 137 + 31543231 = 31543368
- 149 + 31543219 = 31543368
- 151 + 31543217 = 31543368
- 349 + 31543019 = 31543368
Showing the first eight; more decompositions exist.
