Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533784, here are decompositions:
- 11 + 31533773 = 31533784
- 173 + 31533611 = 31533784
- 197 + 31533587 = 31533784
- 251 + 31533533 = 31533784
- 353 + 31533431 = 31533784
- 593 + 31533191 = 31533784
- 617 + 31533167 = 31533784
- 641 + 31533143 = 31533784
Showing the first eight; more decompositions exist.
