Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600800, here are decompositions:
- 17 + 31600783 = 31600800
- 29 + 31600771 = 31600800
- 47 + 31600753 = 31600800
- 59 + 31600741 = 31600800
- 67 + 31600733 = 31600800
- 79 + 31600721 = 31600800
- 83 + 31600717 = 31600800
- 97 + 31600703 = 31600800
Showing the first eight; more decompositions exist.
