Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15030, here are decompositions:
- 13 + 15017 = 15030
- 17 + 15013 = 15030
- 47 + 14983 = 15030
- 61 + 14969 = 15030
- 73 + 14957 = 15030
- 79 + 14951 = 15030
- 83 + 14947 = 15030
- 101 + 14929 = 15030
Showing the first eight; more decompositions exist.
