Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7180, here are decompositions:
- 3 + 7177 = 7180
- 29 + 7151 = 7180
- 53 + 7127 = 7180
- 59 + 7121 = 7180
- 71 + 7109 = 7180
- 101 + 7079 = 7180
- 137 + 7043 = 7180
- 167 + 7013 = 7180
Showing the first eight; more decompositions exist.
