Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31086, here are decompositions:
- 5 + 31081 = 31086
- 7 + 31079 = 31086
- 17 + 31069 = 31086
- 23 + 31063 = 31086
- 47 + 31039 = 31086
- 53 + 31033 = 31086
- 67 + 31019 = 31086
- 73 + 31013 = 31086
Showing the first eight; more decompositions exist.
