Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533264, here are decompositions:
- 5 + 31533259 = 31533264
- 73 + 31533191 = 31533264
- 97 + 31533167 = 31533264
- 131 + 31533133 = 31533264
- 137 + 31533127 = 31533264
- 163 + 31533101 = 31533264
- 167 + 31533097 = 31533264
- 173 + 31533091 = 31533264
Showing the first eight; more decompositions exist.
