Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533270, here are decompositions:
- 11 + 31533259 = 31533270
- 61 + 31533209 = 31533270
- 79 + 31533191 = 31533270
- 103 + 31533167 = 31533270
- 127 + 31533143 = 31533270
- 137 + 31533133 = 31533270
- 151 + 31533119 = 31533270
- 173 + 31533097 = 31533270
Showing the first eight; more decompositions exist.
