Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533432, here are decompositions:
- 19 + 31533413 = 31533432
- 23 + 31533409 = 31533432
- 43 + 31533389 = 31533432
- 53 + 31533379 = 31533432
- 61 + 31533371 = 31533432
- 89 + 31533343 = 31533432
- 163 + 31533269 = 31533432
- 173 + 31533259 = 31533432
Showing the first eight; more decompositions exist.
