Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533282, here are decompositions:
- 13 + 31533269 = 31533282
- 23 + 31533259 = 31533282
- 73 + 31533209 = 31533282
- 139 + 31533143 = 31533282
- 149 + 31533133 = 31533282
- 163 + 31533119 = 31533282
- 181 + 31533101 = 31533282
- 191 + 31533091 = 31533282
Showing the first eight; more decompositions exist.
