Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534986, here are decompositions:
- 5 + 31534981 = 31534986
- 73 + 31534913 = 31534986
- 107 + 31534879 = 31534986
- 113 + 31534873 = 31534986
- 167 + 31534819 = 31534986
- 199 + 31534787 = 31534986
- 229 + 31534757 = 31534986
- 233 + 31534753 = 31534986
Showing the first eight; more decompositions exist.
