Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31084, here are decompositions:
- 3 + 31081 = 31084
- 5 + 31079 = 31084
- 71 + 31013 = 31084
- 101 + 30983 = 31084
- 107 + 30977 = 31084
- 113 + 30971 = 31084
- 173 + 30911 = 31084
- 191 + 30893 = 31084
Showing the first eight; more decompositions exist.
