Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528676, here are decompositions:
- 7 + 31528669 = 31528676
- 43 + 31528633 = 31528676
- 97 + 31528579 = 31528676
- 103 + 31528573 = 31528676
- 229 + 31528447 = 31528676
- 313 + 31528363 = 31528676
- 349 + 31528327 = 31528676
- 397 + 31528279 = 31528676
Showing the first eight; more decompositions exist.
