Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543266, here are decompositions:
- 23 + 31543243 = 31543266
- 43 + 31543223 = 31543266
- 47 + 31543219 = 31543266
- 59 + 31543207 = 31543266
- 103 + 31543163 = 31543266
- 163 + 31543103 = 31543266
- 197 + 31543069 = 31543266
- 199 + 31543067 = 31543266
Showing the first eight; more decompositions exist.
