Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7086, here are decompositions:
- 7 + 7079 = 7086
- 17 + 7069 = 7086
- 29 + 7057 = 7086
- 43 + 7043 = 7086
- 47 + 7039 = 7086
- 59 + 7027 = 7086
- 67 + 7019 = 7086
- 73 + 7013 = 7086
Showing the first eight; more decompositions exist.
