Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534968, here are decompositions:
- 7 + 31534961 = 31534968
- 89 + 31534879 = 31534968
- 97 + 31534871 = 31534968
- 137 + 31534831 = 31534968
- 149 + 31534819 = 31534968
- 167 + 31534801 = 31534968
- 181 + 31534787 = 31534968
- 211 + 31534757 = 31534968
Showing the first eight; more decompositions exist.
