Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71186, here are decompositions:
- 19 + 71167 = 71186
- 43 + 71143 = 71186
- 67 + 71119 = 71186
- 97 + 71089 = 71186
- 127 + 71059 = 71186
- 163 + 71023 = 71186
- 229 + 70957 = 71186
- 307 + 70879 = 71186
Showing the first eight; more decompositions exist.
