Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543314, here are decompositions:
- 13 + 31543301 = 31543314
- 41 + 31543273 = 31543314
- 71 + 31543243 = 31543314
- 83 + 31543231 = 31543314
- 97 + 31543217 = 31543314
- 107 + 31543207 = 31543314
- 151 + 31543163 = 31543314
- 181 + 31543133 = 31543314
Showing the first eight; more decompositions exist.
