Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31538024, here are decompositions:
- 43 + 31537981 = 31538024
- 103 + 31537921 = 31538024
- 163 + 31537861 = 31538024
- 181 + 31537843 = 31538024
- 277 + 31537747 = 31538024
- 283 + 31537741 = 31538024
- 307 + 31537717 = 31538024
- 337 + 31537687 = 31538024
Showing the first eight; more decompositions exist.
