Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529030, here are decompositions:
- 37 + 31528993 = 31529030
- 61 + 31528969 = 31529030
- 199 + 31528831 = 31529030
- 223 + 31528807 = 31529030
- 229 + 31528801 = 31529030
- 307 + 31528723 = 31529030
- 397 + 31528633 = 31529030
- 409 + 31528621 = 31529030
Showing the first eight; more decompositions exist.
