Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4186, here are decompositions:
- 29 + 4157 = 4186
- 47 + 4139 = 4186
- 53 + 4133 = 4186
- 59 + 4127 = 4186
- 107 + 4079 = 4186
- 113 + 4073 = 4186
- 137 + 4049 = 4186
- 167 + 4019 = 4186
Showing the first eight; more decompositions exist.
