Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576084, here are decompositions:
- 17 + 31576067 = 31576084
- 47 + 31576037 = 31576084
- 53 + 31576031 = 31576084
- 83 + 31576001 = 31576084
- 167 + 31575917 = 31576084
- 191 + 31575893 = 31576084
- 251 + 31575833 = 31576084
- 317 + 31575767 = 31576084
Showing the first eight; more decompositions exist.
