Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534992, here are decompositions:
- 11 + 31534981 = 31534992
- 31 + 31534961 = 31534992
- 79 + 31534913 = 31534992
- 113 + 31534879 = 31534992
- 173 + 31534819 = 31534992
- 191 + 31534801 = 31534992
- 193 + 31534799 = 31534992
- 239 + 31534753 = 31534992
Showing the first eight; more decompositions exist.
