Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529348, here are decompositions:
- 79 + 31529269 = 31529348
- 181 + 31529167 = 31529348
- 199 + 31529149 = 31529348
- 241 + 31529107 = 31529348
- 379 + 31528969 = 31529348
- 439 + 31528909 = 31529348
- 541 + 31528807 = 31529348
- 547 + 31528801 = 31529348
Showing the first eight; more decompositions exist.
