Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31538922, here are decompositions:
- 179 + 31538743 = 31538922
- 193 + 31538729 = 31538922
- 211 + 31538711 = 31538922
- 229 + 31538693 = 31538922
- 251 + 31538671 = 31538922
- 269 + 31538653 = 31538922
- 281 + 31538641 = 31538922
- 293 + 31538629 = 31538922
Showing the first eight; more decompositions exist.
