Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533402, here are decompositions:
- 13 + 31533389 = 31533402
- 23 + 31533379 = 31533402
- 31 + 31533371 = 31533402
- 59 + 31533343 = 31533402
- 193 + 31533209 = 31533402
- 211 + 31533191 = 31533402
- 269 + 31533133 = 31533402
- 283 + 31533119 = 31533402
Showing the first eight; more decompositions exist.
