Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15020, here are decompositions:
- 3 + 15017 = 15020
- 7 + 15013 = 15020
- 37 + 14983 = 15020
- 73 + 14947 = 15020
- 97 + 14923 = 15020
- 151 + 14869 = 15020
- 193 + 14827 = 15020
- 199 + 14821 = 15020
Showing the first eight; more decompositions exist.
