Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31116, here are decompositions:
- 37 + 31079 = 31116
- 47 + 31069 = 31116
- 53 + 31063 = 31116
- 83 + 31033 = 31116
- 97 + 31019 = 31116
- 103 + 31013 = 31116
- 139 + 30977 = 31116
- 167 + 30949 = 31116
Showing the first eight; more decompositions exist.
