Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543416, here are decompositions:
- 19 + 31543397 = 31543416
- 67 + 31543349 = 31543416
- 173 + 31543243 = 31543416
- 193 + 31543223 = 31543416
- 197 + 31543219 = 31543416
- 199 + 31543217 = 31543416
- 283 + 31543133 = 31543416
- 313 + 31543103 = 31543416
Showing the first eight; more decompositions exist.
