Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529546, here are decompositions:
- 7 + 31529539 = 31529546
- 67 + 31529479 = 31529546
- 193 + 31529353 = 31529546
- 199 + 31529347 = 31529546
- 277 + 31529269 = 31529546
- 379 + 31529167 = 31529546
- 397 + 31529149 = 31529546
- 439 + 31529107 = 31529546
Showing the first eight; more decompositions exist.
