Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15002, here are decompositions:
- 19 + 14983 = 15002
- 73 + 14929 = 15002
- 79 + 14923 = 15002
- 151 + 14851 = 15002
- 181 + 14821 = 15002
- 223 + 14779 = 15002
- 271 + 14731 = 15002
- 349 + 14653 = 15002
Showing the first eight; more decompositions exist.
