Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529082, here are decompositions:
- 29 + 31529053 = 31529082
- 89 + 31528993 = 31529082
- 113 + 31528969 = 31529082
- 173 + 31528909 = 31529082
- 229 + 31528853 = 31529082
- 239 + 31528843 = 31529082
- 241 + 31528841 = 31529082
- 251 + 31528831 = 31529082
Showing the first eight; more decompositions exist.
