Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528876, here are decompositions:
- 23 + 31528853 = 31528876
- 53 + 31528823 = 31528876
- 179 + 31528697 = 31528876
- 263 + 31528613 = 31528876
- 317 + 31528559 = 31528876
- 443 + 31528433 = 31528876
- 503 + 31528373 = 31528876
- 563 + 31528313 = 31528876
Showing the first eight; more decompositions exist.
