Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529052, here are decompositions:
- 59 + 31528993 = 31529052
- 83 + 31528969 = 31529052
- 199 + 31528853 = 31529052
- 211 + 31528841 = 31529052
- 229 + 31528823 = 31529052
- 239 + 31528813 = 31529052
- 241 + 31528811 = 31529052
- 251 + 31528801 = 31529052
Showing the first eight; more decompositions exist.
