Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533542, here are decompositions:
- 31 + 31533511 = 31533542
- 43 + 31533499 = 31533542
- 163 + 31533379 = 31533542
- 199 + 31533343 = 31533542
- 283 + 31533259 = 31533542
- 409 + 31533133 = 31533542
- 541 + 31533001 = 31533542
- 571 + 31532971 = 31533542
Showing the first eight; more decompositions exist.
