Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18960, here are decompositions:
- 13 + 18947 = 18960
- 41 + 18919 = 18960
- 43 + 18917 = 18960
- 47 + 18913 = 18960
- 61 + 18899 = 18960
- 101 + 18859 = 18960
- 157 + 18803 = 18960
- 163 + 18797 = 18960
Showing the first eight; more decompositions exist.
