Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625986, here are decompositions:
- 5 + 31625981 = 31625986
- 17 + 31625969 = 31625986
- 23 + 31625963 = 31625986
- 47 + 31625939 = 31625986
- 137 + 31625849 = 31625986
- 167 + 31625819 = 31625986
- 179 + 31625807 = 31625986
- 233 + 31625753 = 31625986
Showing the first eight; more decompositions exist.
