Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496994, here are decompositions:
- 5 + 31496989 = 31496994
- 17 + 31496977 = 31496994
- 31 + 31496963 = 31496994
- 37 + 31496957 = 31496994
- 47 + 31496947 = 31496994
- 73 + 31496921 = 31496994
- 131 + 31496863 = 31496994
- 167 + 31496827 = 31496994
Showing the first eight; more decompositions exist.
