Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 14990, here are decompositions:
- 7 + 14983 = 14990
- 43 + 14947 = 14990
- 61 + 14929 = 14990
- 67 + 14923 = 14990
- 103 + 14887 = 14990
- 139 + 14851 = 14990
- 163 + 14827 = 14990
- 193 + 14797 = 14990
Showing the first eight; more decompositions exist.
