Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534398, here are decompositions:
- 29 + 31534369 = 31534398
- 97 + 31534301 = 31534398
- 101 + 31534297 = 31534398
- 127 + 31534271 = 31534398
- 151 + 31534247 = 31534398
- 157 + 31534241 = 31534398
- 167 + 31534231 = 31534398
- 199 + 31534199 = 31534398
Showing the first eight; more decompositions exist.
