Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 139186, here are decompositions:
- 17 + 139169 = 139186
- 53 + 139133 = 139186
- 107 + 139079 = 139186
- 227 + 138959 = 139186
- 263 + 138923 = 139186
- 269 + 138917 = 139186
- 293 + 138893 = 139186
- 317 + 138869 = 139186
Showing the first eight; more decompositions exist.
