Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31531744, here are decompositions:
- 17 + 31531727 = 31531744
- 443 + 31531301 = 31531744
- 743 + 31531001 = 31531744
- 911 + 31530833 = 31531744
- 947 + 31530797 = 31531744
- 971 + 31530773 = 31531744
- 1031 + 31530713 = 31531744
- 1061 + 31530683 = 31531744
Showing the first eight; more decompositions exist.
