Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31016, here are decompositions:
- 3 + 31013 = 31016
- 67 + 30949 = 31016
- 79 + 30937 = 31016
- 157 + 30859 = 31016
- 163 + 30853 = 31016
- 199 + 30817 = 31016
- 313 + 30703 = 31016
- 367 + 30649 = 31016
Showing the first eight; more decompositions exist.
