Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18976, here are decompositions:
- 3 + 18973 = 18976
- 17 + 18959 = 18976
- 29 + 18947 = 18976
- 59 + 18917 = 18976
- 107 + 18869 = 18976
- 137 + 18839 = 18976
- 173 + 18803 = 18976
- 179 + 18797 = 18976
Showing the first eight; more decompositions exist.
