Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534434, here are decompositions:
- 5 + 31534429 = 31534434
- 7 + 31534427 = 31534434
- 11 + 31534423 = 31534434
- 23 + 31534411 = 31534434
- 101 + 31534333 = 31534434
- 137 + 31534297 = 31534434
- 163 + 31534271 = 31534434
- 193 + 31534241 = 31534434
Showing the first eight; more decompositions exist.
