Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61166, here are decompositions:
- 13 + 61153 = 61166
- 37 + 61129 = 61166
- 67 + 61099 = 61166
- 109 + 61057 = 61166
- 139 + 61027 = 61166
- 223 + 60943 = 61166
- 229 + 60937 = 61166
- 277 + 60889 = 61166
Showing the first eight; more decompositions exist.
