Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31538676, here are decompositions:
- 5 + 31538671 = 31538676
- 23 + 31538653 = 31538676
- 47 + 31538629 = 31538676
- 53 + 31538623 = 31538676
- 97 + 31538579 = 31538676
- 107 + 31538569 = 31538676
- 137 + 31538539 = 31538676
- 149 + 31538527 = 31538676
Showing the first eight; more decompositions exist.
