Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61186, here are decompositions:
- 17 + 61169 = 61186
- 179 + 61007 = 61186
- 233 + 60953 = 61186
- 263 + 60923 = 61186
- 269 + 60917 = 61186
- 317 + 60869 = 61186
- 449 + 60737 = 61186
- 467 + 60719 = 61186
Showing the first eight; more decompositions exist.
