Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15012, here are decompositions:
- 29 + 14983 = 15012
- 43 + 14969 = 15012
- 61 + 14951 = 15012
- 73 + 14939 = 15012
- 83 + 14929 = 15012
- 89 + 14923 = 15012
- 181 + 14831 = 15012
- 191 + 14821 = 15012
Showing the first eight; more decompositions exist.
