Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529058, here are decompositions:
- 5 + 31529053 = 31529058
- 61 + 31528997 = 31529058
- 89 + 31528969 = 31529058
- 149 + 31528909 = 31529058
- 227 + 31528831 = 31529058
- 251 + 31528807 = 31529058
- 257 + 31528801 = 31529058
- 307 + 31528751 = 31529058
Showing the first eight; more decompositions exist.
