Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15036, here are decompositions:
- 5 + 15031 = 15036
- 19 + 15017 = 15036
- 23 + 15013 = 15036
- 53 + 14983 = 15036
- 67 + 14969 = 15036
- 79 + 14957 = 15036
- 89 + 14947 = 15036
- 97 + 14939 = 15036
Showing the first eight; more decompositions exist.
